When LLVM sees something like (v1iN (vselect v1i1, v1iN, v1iN)) it can decide that the result is OK (v1i64 is legal on AArch64, for example) but it still need scalarising because of that v1i1. There was no code to do this though. AArch64 and ARM64 have DAG combines to produce efficient code and prevent that occuring in *most* such situations, but there are edge cases that they miss. This adds a legalization to cope with that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205626 91177308-0d34-0410-b5e6-96231b3b80d8
