[X86][InstCombine] Teach SimplifyDemandedVectorElts to handle masked scalar add/sub/mul/div/max/min intrinsics better. Now we can remove these intrinsics if element 0 isn't used. Also fix undef element tracking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@289636 91177308-0d34-0410-b5e6-96231b3b80d8
