Intrin.h: Clean up our atomic intrinsics
Three things:
- The atomic intrinsics mandate memory barriers, let's start emitting
some.
- We don't need to manually create RMW operations, we can just do
__atomic_fetch_foo instead of performing __atomic_foo_fetch and
undoing foo.
- Don't use inline assembly, we don't need it for these intrinsics.
This fixes PR24101.
