1) Improve comments.
2) Don't try to insert an i64 value into the low part of a
vector with movq on an x86-32 target. This allows us to
compile:
__m128i doload64(short x) {return _mm_set_epi16(0,0,0,0,0,0,0,1);}
into:
_doload64:
movaps LCPI1_0, %xmm0
ret
instead of:
_doload64:
subl $28, %esp
movl $0, 4(%esp)
movl $1, (%esp)
movq (%esp), %xmm0
addl $28, %esp
ret
