Matheus Castanho 41f013cef2 powerpc: Use scv instruction on clone when available 
clone already uses r31 to temporarily save input arguments before doing the
syscall, so we use a different register to read from the TCB. We can also avoid
allocating another stack frame, which is not needed since we can simply extend
the usage of the red zone.
