* [Arm64] Don't use D-copies in CopyBlock (#63588)

* Increase the maximum number of internal registers allowd per node in src/coreclr/jit/lsra.h

* Based on discussion in https://github.com/dotnet/runtime/issues/63453 don't allocate a SIMD register pair if the JIT won't be able to use Q-copies in src/coreclr/jit/lsraarmarch.cpp

* Update CodeGen to reflect that Q-copies should be used only when size >= 2 * FP_REGSIZE_BYTES and using of them makes the instruction sequence shorter in src/coreclr/jit/codegenarmarch.cpp

* Fix Crossgen2 bug #61104 and add regression test (#63956)

The issue tracks the runtime regression failure where
Crossgen2-compiled app is unable to locate a type with non-ASCII
characters in its name. The failure was caused by the fact that
Crossgen2 was incorrectly zero-extending the individual UTF8 characters
when calculating the hash whereas runtime is sign-extending them.

* Fix invalid threading of nodes in rationalization (#64012)

The code in question assumes that the ASG will be
reversed and thus threads "simdTree" before "location"
in the linear order. That dependency, while valid,
because "gtSetEvalOrder" will always reverse ASGs
with locals on the LHS, is unnecessary and incorrect
from the IR validity point of view.

Fix this by using "InsertAfter" instead of manual
node threading.

* Fix issues with verify_regions, clear_batch_mark_array_bits. (#63798)

Details:
- we cannot verify the tail of the region list from background GC, as it may be updated by threads allocating.
- fix case in clear_batch_mark_array_bits where end is equal to the very end of a segment and we write into uncommitted memory in the mark_array.
-  bgc_clear_batch_mark_array_bits did some checks and then called clear_batch_mark_array_bits which repeated the exact same checks. Renamed clear_batch_mark_array_bits to bgc_batch_mark_array_bits and removed the old copy, removed the declaration for clear_batch_mark_array_bits.

* Fix exception propagation over HW exception frame on macOS arm64 (#63596)

* Fix exception propagation over HW exception frame on macOS arm64

There is a problem unwinding over the PAL_DispatchExceptionWrapper
to the actual hardware exception location. The unwinder is unable
to get distinct LR and PC in that frame and sets both of them to
the same value. This is caused by the fact that the
PAL_DispatchExceptionWrapper is just an injected fake frame and
there was no real call. Calls always return with LR and PC set
to the same value.

The fix unifies the hardware exception frame unwinding with Linux
where we had problems unwinding over signal handler trampoline, so
PAL_VirtualUnwind skips the trampoline and now also the
PAL_DispatchExceptionWrapper frame by copying the context of
the exception as the unwound context.

* Make ILLink validation steps in libs incrementally buildable (#64041)

* Make ILLink validation steps in libs incrementally buildable

Both the illink-oob and the illink-sharedframework targets don't define Inputs and Outputs which makes them run during no-op incremental builds. This change defines Inputs and Outputs based on what's used during the target's execution so that if the input assemblies or the illink assembly itself haven't changed, the step will be skipped.

Also renaming properties and items to make them more readable and consistent. As these target files are "extensions" of the src.proj file and aren't shared anywhere, they can be treated like logic inside a project file and hence prefixing properties and items with an underscore "_" isn't necessary.

delete redundant code, fix up one case of wrong typing
for a constant in the MUL -> SHIFT optimization.

One CSE diff due to different VNs because of the typing
change for the constant (int -> long).

Many text diffs: "mov x3, 5" => "mov w3, 5".

* Do not set GTF_NO_CSE for sources of block copies (#63462)

It is not necessary, the compiler fully supports locals
on the RHS of a struct assignment. Not marking these results
in a CQ improvement, from struct (including SIMD) CSEs and
global constant propagation into promoted fields.

* Handle embedded assignments in copy propagation (#63447)

* Clean things up a little

Delete redundant conditions, use "LclVarDsc*", rename locals for clarity.

* Delete a redundant condition

For actual def nodes, GTF_VAR_CAST will never be set, it is
only set in "optNarrowTree" for uses.

For "def nodes" that are actually uses (parameters), the VNs
will never match anyway.

* Handle embedded assignments in copy propagation

Previously, as the comments in copy propagation tell us, it
did not handle "intervening", or not-top-level definitions of
locals, instead opting to maintain a dedicated kill set of them.

This is obviously a CQ problem, but also a TP one, as it meant
there had to be a second pass over the statement's IR, where
the definitions would be pushed on the stack.

This change does away with that, instead pushing new definitions
as they are encountered in execution order, and simultaneously
propagating on uses. Notably, this means the code now needs to
look at the real definition nodes, i. e. ASGs, not the LHS locals,
as those are encountered first in canonical execution order, i. e.
for a tree like:

```
  ASG
    LCL_VAR V00 "def"
    ADD
      LCL_VAR V00
      LCL_VAR V00
```

Were we to use the "def" as the definition point, we would wrongly
push it as the definition on the stack, even as the assignments
itself hasn't happened yet at that point.

There are nice diffs with this change, all resulting from unblocked
propagations, and mostly coming from setup arguments under calls.

* Make ApiCompat.proj incrementally buildable (#64037)

* Make ApiCompat.proj incrementally buildable

In https://github.com/dotnet/runtime/pull/64000, I noticed that ApiCompat.proj never builds incrementally. Even though the RunApiCompat target has Inputs and Outputs, those aren't defined too late inside the target to have any effect. Moving them out and declare the generated response file as an output.

Also simplifying some msbuild logic and renaming some properties as underscore prefixes in project files don't make sense if the property isn't reserved in any way.

* Address-expose locals under complex local addresses in block morphing (#63100)

* Handle complex local addresses in block morphing

In block morphing, "addrSpill" is used when the destination or source
represent indirections of "complex" addresses. Unfortunately, some trees
in the form of "IND(ADDR(LCL))" fall into this category.

If such an "ADDR(LCL)" is used as an "addrSpill", the underlying local
*must* be marked as address-exposed. Block morphing was using a very
simplistic test for when that needs to happen, essentially only recognizing
"ADDR(LCL_VAR/FLD)". But it is possible to have a more complicated pattern
as "PrepareDst/Src" uses "IsLocalAddrExpr" to recognize indirect stores
to locals.

Currently it appears impossible to get a mismatch here as morph transforms
"IND(ADD(ADDR(LCL_VAR), OFFSET))" into "LCL_FLD" (including for TYP_STRUCT
indirections), but this is a very fragile invariant. Transforming TYP_STRUCT
GT_FIELDs into GT_OBJs instead of GT_INDs breaks it, for example.

Fix this by address-exposing the local obtained via "IsLocalAddrExpr".

This is mostly motivated by NativeAOT subset builds where SPMI contributes to 10% of the native build time (nativeaot CorecLR subset builds pretty quickly compared to full CoreCLR).

* Update NativeAOT codegen and Crossgen2 for CreateSpan (#63977)

- Make sure FieldRVA pointers remain aligned as required by the code generator
  - Use the same Packing Size approach as the IL Linker will use (See jbevain/cecil#817 for details)
  - Compilers that generate CreateSpan will need to follow that trick to be compatible with rewriters.
- Provide ECMA spec augment describing packing size detail

* Add alignment to mapped field stream (#63305)

* Align MappeFieldDataStream at 8 byte boundary

* Add test to verify that the mapped field rva data blob is aligned to ManagedPEBuilder.MappedFieldDataAlignment

* Only align when the mapped field data is of size not equal to 0

* Implement hash and HMAC stream one shots 

This implements hashing and HMAC statics for streams. Additionally,
"LiteHmac" and "LiteHash" were introduced. The existing HMAC and hash
provider functionality do some bookkeeping we don't need for resetting.
Since we do not need to use these hash handles after the digest has
been finalized, resetting is unnecessary work. For HMAC, that also means
keeping a copy of the key around for some implementations which we don't
need to do.

The LiteHash and LiteHmac types are implemented as structs with a common
interface. To avoid boxing, generics are used and constrained to the interface
where possible.

The Browser implementation just defers to the existing HashDispenser rather
than do anything novel.

The HashProviderCng is somewhat specialized in its ability to reset. It did
up-front check to determine if the platform supported reusable hash providers,
and further had a single implementation for HMAC and Digests. The current
Lite hash design requires that they remain separate types.

* Port MD4 managed implementation from mono/mono (#62074)

Porting MD4 managed implementation from mono/mono (MD4.cs and MD4Managed.cs). 
  
It adds:  
- an internal class in the System.Net.Security with a single HashData method for now;  
- a set of related MD 4 unit tests to System.Net.Security.Unit.Tests project.

* Fix one source of perf regression in GCHeap::Alloc. This impacts the System.Collections.CtorFromCollectionNonGeneric<Int32> family of benchmarks. (#64091)

These benchmarks manage to make GCHeap::Alloc into a hotspot, so the call to IsHeapPointer() at the end matters for performance.

* Add blsr (#63545)

* Fix FileSystemAclExtensions.Create when passing a null FileSecurity (#61297)

* Make FileSecurity parameter nullable.

* Add missing ArgumentException message for FileMode.Append.

* Refactor tests to ensure FileSecurity is tested with all FileMode and FileSystemRights combinations. Separate special cases.

* Remove exception that throws when FileSecurity is null.
Ensure we have logic that can create a FileHandle when FileSecurity is null.
Fix bug where FileShare.Inheritable causes IOException because it is being unexpectedly passed to the P/Invoke (it should just be saved in the SECURITY_ATTRIBUTES struct).
Add documentation to mention this parameter as optional.
Ensure all exceptions match exactly what we have in .NET Framework, with simpler logic.

* Address suggestions

* Tune FP CSEs live across a call better (#63903)

The problem was that the comparison of a weighted refcount,
which usually has the order of hundreds or tens, with a small
digit like "4" was too weak and missed some cases where we
were still trying to CSE cheaps floats across calls and ending
up with lots of stack shuffling.

Fix this by using different tuning parameters, namely the costs
estimated for the uses and defs (increase them to account for
the spills and reloads).

* Add missing handle function enter/return macros (#64061)

The mono_field_static_get_value method uses a handle, but did not set up
enter/exit macros properly, so this handle was leaked.

Some code in Unity calls this embedding API method pretty often, which
can lead to the mark stack overflowing in the GC code.

* Fix remote unwind (#64220)

The _OOP_find_proc_info was setting only a couple of members of the
unw_dyn_info_t instance on stack. So the remaining ones had random
values. The load_offset was a recently added member to the struct.
When we have updated libunwind, this change came in. The load_offset was
random and that has broken unwindign as this offset is subtracted from
the IP when looking up unwind info.

The fix clears the whole struct. I have verified that the issue we had no
longer happens with the fix.

* Android remove backward timezones (#64028)

Fixes #63693

It was discovered that Android produces duplicate TimeZone DisplayNames among all timezone IDs in GetSystemTimeZones. These duplicate DisplayNames occur across TimeZone IDs that are aliases, where all except one are backward timezone IDs.

If a name is changed, put its old spelling in the 'backward' file

From the Android TimeZone data file tzdata, it isn't obvious which TimeZone IDs are backward (I find it strange that they're included in the first place), however we discovered that on some versions of Android, there is an adjacent file tzlookup.xml that can aid us in determining which TimeZone IDs are "current" (not backward).

This PR aims to utilize tzlookup.xml when it exists and post-filter's the Populated TimeZone IDs in the AndroidTzData instance by removing IDs and their associated information (byteoffset and length) from the AndroidTzData instance if it is not found in tzlookup.xml. This is using the assumption that all non-backward TimeZone IDs make it to the tzlookup.xml file.

This PR also adds a new TimeZoneInfo Test to check whether or not there are duplicate DisplayNames in GetSystemTimeZones

not exist.

* Support {Last}IndexOfAny with sets after {lazy} loops (#64254)

When emitting backtracking loops, the loop consumes as much and then backtracks through the consumed input.  Rather than doing this one character by one character, we previously added use of LastIndexOf to search for the next place the literal after the loop matches.  We can also augment that to use IndexOfAny to search for a small set that comes after a loop instead of a literal.

Similarly when emitting backtracking lazy loops, rather than consuming one character and trying the rest of the expression and then consuming another character and trying the rest of the expression, we previously added an optimization to use IndexOf{Any} to find the next possible location of a match based on the literal that comes after the lazy loop.  And we can similarly augment that to support a small set after the lazy loop.

This is particularly helpful for IgnoreCase, as we're on a path to replacing literals with sets that contain all equivalent casings of that character.

* Fix race conditions in SystemEvents shutdown logic (#62773)

* Fix race conditions in SystemEvents shutdown logic

When the application is terminated through Restart Manager the event broadcasting window will get the `WM_CLOSE` message. The message gets handled by passing it to `DefWndProc` which calls `DestroyWindow` on the window itself thus making the window handle invalid. The `Shutdown` method expects the window handle to be valid to post `WM_QUIT` message to terminate the thread running the message loop but that's no longer possible under these conditions.

Additionally there's second race condition with the `s_eventThreadTerminated` event that is created during shutdown and set conditionally. A race condition between the threads could cause it to be created when the window message thread is already shutting down and thus it would never be set. Waiting for it in the `Shutdown` method would be cause a deadlock. This thread is also completely unnecessary since a `Join` is performed on the thread itself.

The fix has several changes that act together:
- `s_eventThreadTerminated` event is removed completely in favor of only relying on `Thread.Join`
- `WM_DESTROY` message is detected (which happens as a result of WM_CLOSE calling `DefWndProc` which in turn calls `DestroyWindow`) and handled by shutting down the message loop thread
- The message loop itself is rewritten to use standard `GetMessageW` loop. The reasoning on why it was not used seems not to be valid anymore since AppDomain shutdowns are performed differently

* Add unit test.

* Add braces

* Add marshaller for TypeLoad failure cases (#64317)

This is marshaller used when there incorrect configuration of marshaller applied to fields mostly

* Add additional loop table asserts (#64126)

1. Assert that top-level loops are basic block disjoint
2. Assert LPFLG_ITER related flags are legal

In addition:
1. Create a `optClearLoopIterInfo` phase to clear various bits in the loop
table that are known to no longer be valid, to prevent bad asserts or JitDump
output on their values.
2. Move the EndPhase call in Phase::PostPhase happens early, not late.
This causes any subsequent asserts due to post-phase checking to be
marked with the correct phase, in cases where there was a nested phase
executed (such as liveness re-computation).
3. Convert PHASE_INSERT_GC_POLLS to use EndPhase checking
4. Convert fgDetermineFirstCodeBlock to return a PhaseStatus
5. Some minor cleanup in optUpdateLoopsBeforeRemoveBlock()
(this was extracted from some bigger changes)

* Moved AssemblyName helpers to managed (part 2) (#63915)

* implement GetAssemblyName via dynamic call to MetadataReader

* A few more file-locking tests.

* fix #28153

* no need for version when getting MetadataReader

* rename the argument to match AssemblyName

* perf tweaks

* use memory-mapped file to read metadata

* adjust tests for the new implementation

* use "bufferSize: 1" when stream is going to be mapped.

* null-conditional operator.

* do Dispose before re-throwing

* get rid of the platform-specific/native stuff

* remove assemblyname.hpp

* remove `VerifyIsAssembly()`

* PR feedback

* put back gStdMngIEnumerableFuncs and the others

* Fix several bugs in NullabilityInfoContext. (#64143)

* Fix several bugs in NullabilityInfoContext.

* Reverse ASG(CLS_VAR, ...) (#63957)

This helps with register allocation. Consider:
```
***** BB01
STMT00001 ( 0x000[E-] ... ??? )
N003 ( 18, 10) [000003] -ACXG-------              *  ASG       ref    $c0
N001 (  3,  4) [000002] ----G--N----              +--*  CLS_VAR   ref    Hnd=0x8fec230 Fseq[hackishFieldName]
N002 ( 14,  5) [000000] --CXG-------              \--*  CALL      ref    CscBench.GetMscorlibPathCore $c0
```
The rationalizer will rewrite it to what is effectively:
```
***** BB01
STMT00001 ( 0x000[E-] ... ??? )
N004 ( 18, 12) [000003] -ACXG---R---              *  ASG       ref
N003 (  3,  6) [000002] n---G--N----              +--*  IND       ref
N002 (  1,  4) [000006] H-----------              |  \--*  CLS_VAR_ADDR byref  Hnd=0x8fec230
N001 ( 14,  5) [000000] --CXG-------              \--*  CALL      ref    CscBench.GetMscorlibPathCore
```
And the final LIR will look like:
```
               [000006] ------------                 IL_OFFSET void   INLRT @ 0x000[E-]
N001 (  3,  4) [000002] ----G--N----         t2 =    CLS_VAR_ADDR byref  Hnd=0x8fec230
N002 ( 14,  5) [000000] --CXG-------         t0 =    CALL      ref    CscBench.GetMscorlibPathCore $c0
                                                  /--*  t2     byref
                                                  +--*  t0     ref
N003 ( 18, 10) [000003] -A-XG-------              *  STOREIND  ref
               [000007] ------------                 IL_OFFSET void   INLRT @ 0x00A[E-]
N001 (  0,  0) [000004] ------------                 RETURN    void   $180
```
Since this store must use a barrier, `CLS_VAR_ADDR` won't be contained and will have to be evaludated
separately. Because its value is live across a call, it'll get spilled and reloaded. Reversing the ASG
fixes the problem:
```
------------ BB01 [000..00B) (return), preds={} succs={}
               [000006] ------------                 IL_OFFSET void   INLRT @ 0x000[E-]
N001 ( 14,  5) [000000] --CXG-------         t0 =    CALL      ref    CscBench.GetMscorlibPathCore $c0
N002 (  3,  4) [000002] ----G--N----         t2 =    CLS_VAR_ADDR byref  Hnd=0x8fec230
                                                  /--*  t2     byref
                                                  +--*  t0     ref
N003 ( 18, 10) [000003] -A-XG-------              *  STOREIND  ref
               [000007] ------------                 IL_OFFSET void   INLRT @ 0x00A[E-]
N001 (  0,  0) [000004] ------------                 RETURN    void   $180
```

* Fixes a few issues for dprintf on OSX (#64076)

* [Codespaces] Make it possible to run wasm samples in the browser (#64277)

With these changes, running the following in the Codespace will open the local browser to a page served from the codespace hosting the WASM sample:

```console
cd src/mono/sample/wasm/browser
make
make run-browser
```


* Set EMSDK_PATH in .devcontainer.json

   We provision Emscripten as part of the devcontainer prebuild.

   Set EMSDK_PATH to allow rebuilding the wasm runtime to work without any additional ceremony

* Install dotnet-serve into .dotnet-tools-global

* [wasm] Don't try to open browser if running in Codespaces

* .devcontainer: add global tools dir to PATH

* .devcontainer: forward port 8000

   This enables running the mono wasm samples in the local browser:

* [wasm] samples: also check for dotnet-serve on the path

   On Codespaces we install dotne…
