It looks like the allocate_stack_worker instructions need the guards the
pro_epilogue_adjust_stack instructions have to prevent instructions
that use the frame pointer from being moved around these instructions.
They should also probably get the RTX_FRAME_RELATED_P flags that the
pro_epilogue_adjust_stack instructions get.
