Nice.  I tweaked it to avoid the fpstack stuff on x86-32.  I'm now  


         subl    $12, %esp
         movss   LCPI1_0, %xmm0
         mulss   16(%esp), %xmm0
         movss   %xmm0, (%esp)
         call    L_qux$stub
         movss   LCPI1_0, %xmm1
         mulss   %xmm1, %xmm0
         addl    $12, %esp


         subq    $8, %rsp
         movss   LCPI1_0(%rip), %xmm1
         mulss   %xmm1, %xmm0
         call    _qux
         movss   LCPI1_0(%rip), %xmm1
         mulss   %xmm1, %xmm0
         addq    $8, %rsp

Both look great, but we should still fold the remat load into the  
muls :)
