At least VS2005 (what I'm using) won't compile resample_sse.h with
_USE_SSE2 defined because it refuses to cast __m128 to __m128d and vice
versa. While there are intrinsics to do the casts, I thought it would be
simpler to just use an intrinsic that accomplishes the same thing
without all the casting.
