Pull in r282174 from upstream llvm trunk (by Krzysztof Parzyszek):
[PPC] Set SP after loading data from stack frame, if no red zone is present Follow-up to r280705: Make sure that the SP is only restored after all data is loaded from the stack frame, if there is no red zone. This completes the fix for https://llvm.org/bugs/show_bug.cgi?id=26519. Differential Revision: https://reviews.llvm.org/D24466
