re PR target/32337 (Error: Register number out of range 0..1)

	PR target/32337
	* config/ia64/ia64.c (find_gr_spill): Don't decrement
	current_frame_info.n_local_regs.  Don't return emitted local
	regs.
	(ia64_compute_frame_size): Improve unwind hack to put
	RP, PFS, FP in that order by allowing some of the registers
	been already emitted, as long as they are emitted to the
	desired register.
