Hi Matt,

I've added the AVX part of this in r137090. But keep in mind that if you want
to generate cmp*ps/pd variants you should sign extended the result, so in the
correct testcase is:

define <8 x i32> @cmp00(<8 x float> %a, <8 x float> %b) nounwind readnone {
  %bincmp = fcmp olt <8 x float> %a, %b
  %s = sext <8 x i1> %bincmp to <8 x i32>
  ret <8 x i32> %s
}
