New Revision: 173366

URL: http://llvm.org/viewvc/llvm-project?rev=173366&view=rev
Log:
Start cleanup of PPC register definitions using foreach loops.

No functionality change intended.

This captures the first two cases GPR32/64. For the others, we need
an addition operator (if we have one, I've not yet found it).

Based on a suggestion made by Tom Stellard in the AArch64 review!
