[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.
