[PATCH] D31908: [AntiDepBreaker] Don't rename callee saved register restore instruction

Ah, I remember---it was the reverse problem: renaming other register into a restored callee-saved register.

In any case, the problem that this patch is trying to fix still doesn't apply to Hexagon.  We add all of the clobbered callee-saved register as implicit uses to the return instructions.
