New Revision: 70555

URL: http://llvm.org/viewvc/llvm-project?rev=70555&view=rev
Log:
Make RequiresTypeConversion canonicalize the types before calling the
target hooks canLosslesslyBitCastTo and isTruncateFree. This allows
targets to avoid worrying about handling all combinations of integer
and pointer types.
