[PATCH][AVX512] Fix scalar floating point select.

[Demikhovsky, Elena]

+; CHECK-LABEL: @select02
+; CHECK: cmpless           %xmm0, %xmm3, %k1
+; CHECK-NEXT: vmovups            %zmm2, %zmm1 {%k1}
+define float @select02(float %a, float %b, float %c, float %eps) {
+  %cmp = fcmp oge float %a, %eps
+  %cond = select i1 %cmp, float %c, float %b
+  ret float %cond
+}

Some comments:


1)      Please use VMOVSS xmm1 {k1}{z}, xmm2, xmm3 instead of VMOVUPS.

2)      Why "oge" has been translated to "le" and not to "lt" ?
