Added scalar compare VCMPSS, VCMPSD. Implemented LowerSELECT for scalar FP operations. I replaced FSETCCss, FSETCCsd with one node type FSETCCs. Node extract_vector_elt(v16i1/v8i1, idx) returns an element of type i1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197384 91177308-0d34-0410-b5e6-96231b3b80d8
