LowerVSELECT will, if possible, generate a X86ISD::BLENDI DAG node if the condition is constant and we can emit that instruction, given the subtarget. This is not enough for all cases. An additional SELECTCombine optimization will be committed. Fixed tests that were expecting variable blends but where a blend+imm can be generated. Added test where we can't emit blend+immediate. Added avx2 blend+imm tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209043 91177308-0d34-0410-b5e6-96231b3b80d8
