[PATCH] D15930: Prevent renaming of CR fields in AADB when a CR restore is present

[Nemanja Ivanovic via llvm-commits]

We should also consider whether we should set the flags on the MTCRF/MFCRF instructions. There currently does not appear to be a need for that since the only way we emit that instruction is in the assembly output (PPCAsmPrinter.cpp). However, if we decide to use that instruction in the future to save/restore multiple CR fields at a time, we should consider the effect that AADB will have on it.
