[PATCH] D20847: BitCast infinite loop fix

[Guozhi Wei via llvm-commits]

Carrot added a comment.

optimizeBitCastFromPhi only generates BitCast for load/store instructions, and BitCast with load/store instructions can easily be handled by InstCombineLoadStoreAlloca.cpp. So one solution to the problem is if all users of a CI are load/store instructions, we should not do optimizeBitCastFromPhi on it.
