[X86] Add inline assembly versions of _InterlockedExchange_HLEAcquire/Release and _InterlockedCompareExchange_HLEAcquire/Release for MSVC compatibility.

Clang/LLVM doesn't have a way to pass an HLE hint through to the X86 backend to emit HLE prefixed instructions. So this is a good short term fix.
