<pre>Not sure which of the shuffle changes actually fixed this, but currently top of
trunk does the right thing for the attached example:
movq 56(%rsp), %rax
pmovzxbd (%rax), %xmm0 # xmm0 =
mem[0],zero,zero,zero,mem[1],zero,zero,zero,mem[2],zero,zero,zero,mem[3],zero,zero,zero
movdqa %xmm0, 32(%rsp)</pre>
