[SelectionDAG][X86] Enable iX SimplifyDemandedBits to vXi1 SimplifyDe…
…mandedVectorElts simplification. Add a hack to X86 to avoid a regression Patch showing the effect of enabling bool vector oversimplification. Non-VLX builds can simplify a kshift shuffle, but VLX builds simplify: insert_subvector v8i zeroinitializer, v2i --> insert_subvector v8i undef, v2i Preventing the removal of the AND to clear the upper bits of result Differential Revision: https://reviews.llvm.org/D53022 llvm-svn: 369780
