Here are a few miscellaneous things to tidy up the PPC64 fast-isel implementation. I corrected a couple of commentary lapses, and added documentation of future opportunities. I also implemented TargetMaterializeAlloca, which I somehow forgot when I split up the original huge patch. Finally, I decided to delete SelectCmp. I hadn't previously hooked it in to TargetSelectInstruction(), and when I did I realized it wasn't serving any useful purpose. This is only useful for compares that don't feed a branch in the same block, and to handle that we would have to have logic to interpret i1 as a condition register. This could probably be done, but would require Unseemly Hackery, and honestly does not seem worth the hassle. This ends the current patch series. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189715 91177308-0d34-0410-b5e6-96231b3b80d8
