[X86] Improved target specific combine on VSELECT dag nodes.
This patch teaches function 'transformVSELECTtoBlendVECTOR_SHUFFLE' how to convert VSELECT dag nodes to shuffles on targets that do not have SSE4.1. On pre-SSE4.1 targets, we can still perform blend operations using movss/movsd. Also, removed a target specific combine that performed a premature lowering of VSELECT nodes to target specific MOVSS/MOVSD nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222647 91177308-0d34-0410-b5e6-96231b3b80d8
