  Log Message:
  -----------
  Use Address for CGBuilder's CreateAtomicRMW and CreateAtomicCmpXchg. (#74349)

Update all callers to pass through the Address.

For the older builtins such as `__sync_*` and MSVC `_Interlocked*`,
natural alignment of the atomic access is _assumed_. This change
preserves that behavior. It will pass through greater-than-required
alignments, however.
