Any forward declarations of _mm_prefetch in any ms headers are compatible
with the definition provided in xmmintrin.h provided by Intel. Microsoft
actually uses Intel's headers rather than making up their own like we and
gcc do, thus automatically making them signature compatible with what Intel
publishes. I am presently assuming that any issues with incorrect uses of
_mm_prefetch accepting non-char pointers all stem from clang's macro
enabling incorrect usage.
