[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.
