  Log Message:
  -----------
  [X86] Enabled a bunch of 64-bit Interlocked* functions intrinsics on 32-bit Windows to match recent MSVC

This enables _InterlockedAnd64/_InterlockedOr64/_InterlockedXor64/_InterlockedDecrement64/_InterlockedIncrement64/_InterlockedExchange64/_InterlockedExchangeAdd64/_InterlockedExchangeSub64 on 32-bit Windows

The backend already knows how to expand these to a loop using cmpxchg8b on 32-bit targets.

Fixes PR46595
