[LRA]: Implement output stack pointer reloads
LRA prohibited output stack pointer reloads but it resulted in LRA
failure for AVR target which has no arithmetic insns working with the
stack pointer register. Given patch implements the output stack
pointer reloads.
gcc/ChangeLog:
* lra-constraints.cc (goal_alt_out_sp_reload_p): New flag.
(process_alt_operands): Set the flag.
(curr_insn_transform): Modify stack pointer offsets if output
stack pointer reload is generated.
