    [LRA]: Process output stack pointer reloads before emitting reload insns
    
    Previous patch setting up asserts for processing stack pointer reloads
    caught an error in code moving sp offset.  This resulted in failure of
    building aarch64 port. The code wrongly processed insns beyond the
    output reloads of the current insn.  This patch fixes it.
    
    gcc/ChangeLog:
    
            * lra-constraints.cc (curr_insn_transform): Process output stack
            pointer reloads before emitting reload insns.
