The DumpGen SOS unit test is failed under USE_REGIONS

[cshung]

It looks like a possible cause is that we haven't implement microsoft/clrmd#936 yet.

Is there any way you could fix this?

[cshung]

In order to fix this bug, we need to

1. Get the DAC to expose the data so that we can properly walk the heap under USE_REGIONS . Fix DacHeapWalker for USE_REGIONS runtime#56796 should fix it.

2. Get CLRMD to expose the data so that DumpGen can access it. Support regions microsoft/clrmd#945 should fix it.

3. Get a new version of CLRMD published, and

4. Get this repo to depends on the new version.

None of these is very difficult, I could fix them, but it will probably take some time before we can complete them all.

Other than your current runtime PR (which hopefully can get merged before Tuesday) all of this sounds like out of band work in clrmd/diagnostics. I was hoping you could eventually do this work when you have time because the diagnostic team is a little overbooked and under staffed. If you can do this work (Lee can probably help with the clrmd work), please assign this issue to yourself.

I verified that #2547 fixed the issue, the test is now passing for USE_REGIONS.
