Just include xmmintrin.h on MSVC as well

The xmmintrin.h as shipped with recent Visual C++ (2003+) provides
_mm_shuffle_pi16 and _mm_mulhi_pu16, so including that header
will do for using these functions, and MSVC does not like the GCC-specific
implementations of _mm_shuffle_pi16 and _mm_mulhi_pu16 that is
currently in the code.

_MM_SHUFFLE is declared in the same way in MSVC's xmmintrin.h, so don't
re-define it here to avoid a compilation warning.
