# Summary

Add `AtomicI32` and `AtomicU32`.

# Motivation

Atomic operations on these types are necessary to interact with certain system
APIs, e.g., futexes.

# Detailed design

Copy `AtomicIsize` and `AtomicUsize` and then `s/size/32/`.

# Drawbacks

More wrappers for what should simply be freestanding functions.

No. Such freestanding functions would have to be intrinsics (not wrappers) and would have to be unsafe.
