crossing and generally work more like the blend emission code in the new vector shuffle lowering. My goal is to have the new vector shuffle lowering just produce VSELECT nodes that are either matched here to BLENDI or are legal and matched in the .td files to specific blend instructions. That seems much cleaner as there are other ways to produce a VSELECT anyways. =] No *observable* functionality changed yet, mostly because this code appears to be near-dead. The behavior of this lowering routine did change though. This code being mostly dead and untestable will change with my next commit which will also point some new tests at it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218588 91177308-0d34-0410-b5e6-96231b3b80d8
