In AVX, it is better to use the appropriate integer or floating point
moves depending on which instructions produce/consume these moves, since
there can be a delay moving from integer to floating point domain. On
SSE systems, it is less important, and we can move movaps/movups which
is 1 byte shorter than movdqa/movdqu.
This patch cleans up a couple of places, and defines macro-assembler
functions Movdqa, Movdqu, Movapd, to call into movaps/movups when AVX is
not supported.
