teach scev to analyze X*4|1 like X*4+c. This allows us to produce:
LBB1_1: #bb
movdqa (%esi), %xmm2
movaps %xmm2, %xmm3
punpcklbw %xmm0, %xmm3
movaps %xmm3, %xmm4
punpcklwd %xmm0, %xmm4
cvtdq2ps %xmm4, %xmm4
mulps %xmm1, %xmm4
movaps %xmm4, (%edi)
leal 1(,%eax,4), %ebx
shll $4, %ebx
punpckhwd %xmm0, %xmm3
cvtdq2ps %xmm3, %xmm3
