Revert r133452: "Emit movq for 64-bit register to XMM register moves..."
...
This is breaking compiler-rt and llvm-gcc builds on MacOSX when not using
the integrated assembler.

Emit movq for 64-bit register to XMM register moves, but continue to accept

Prefer movlhps over punpcklqdq, etc. in more cases.

Teach SD some vector identities, allowing us to compile vec_set-9 into:
...
_test3:
movd %rdi, %xmm1
#IMPLICIT_DEF %xmm0
punpcklqdq %xmm1, %xmm0
ret
instead of:
_test3:
#IMPLICIT_DEF %rax
movd %rax, %xmm0
movd %rdi, %xmm1
punpcklqdq %xmm1, %xmm0
ret
This is still not ideal. There is no reason to two xmm regs.
