Remove unused InterlockedExchange/ReadWriteBarrier declarations (VC/x86)

* src/atomic_ops/sysdeps/msftc/common32_defs.h (_InterlockedExchange,
_ReadWriteBarrier): Remove pragma for unused intrinsic.
* src/atomic_ops/sysdeps/msftc/x86_64.h (_ReadWriteBarrier,
_InterlockedExchange64): Likewise.
* src/atomic_ops/sysdeps/msftc/common32_defs.h (_InterlockedExchange):
Remove unused macro and prototype.
