Now generating perfect (I think) code for "vector set" with a single non-zero
scalar value.
e.g.
_mm_set_epi32(0, a, 0, 0);
==>
movd 4(%esp), %xmm0
pshufd $69, %xmm0, %xmm0
_mm_set_epi8(0, 0, 0, 0, 0, a, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
==>
movzbw 4(%esp), %ax
movzwl %ax, %eax
pxor %xmm0, %xmm0
pinsrw $5, %eax, %xmm0
