I had thought that MSVC does not permit reinterpret casting from FP 
to integer without register store and reload, however this 
stackoverflow 
https://stackoverflow.com/questions/13631951/bitwise-cast-from-m128-to
-m128i-on-msvc says you can tell MSVC to not error out during the 
cast using the magic _mm_castpd_si128 intrinsic.

Useful to know. Thanks.
