[PPC] Claim stack frame before storing into it, if no red zone is present Unlike PPC64, PPC32/SVRV4 does not have red zone. In the absence of it there is no guarantee that this part of the stack will not be modified by any interrupt. To avoid this, make sure to claim the stack frame first before storing into it. This fixes https://llvm.org/bugs/show_bug.cgi?id=26519.
