[PATCH] D17350: [AArch64][ShrinkWrap] Fix bug in prolog clobbering live reg when shrink wrapping.

[Geoff Berry via llvm-commits]

FWIW, this patch is basically a cut and paste from the PPC code, with some simplification done since AArch64 doesn't need a scratch register in the epilog.  I believe this same potential bug would be present for PPC currently as well.
