	(schedule_reg_move): New function.
	(schedule_reg_moves): Call extend_node_sched_params and
	schedule_reg_move.  Extend size of uses bitmap.  Initialize
	num_consecutive_stages.  Return false if a move could not be
	scheduled.
	(apply_reg_moves): Don't emit moves here.
	(permute_partial_schedule): Handle register moves.
	(duplicate_insns_of_cycles): Remove for_prolog.  Emit moves according
	to the same stage-count test as ddg nodes.
	(generate_prolog_epilog): Update calls accordingly.
	(sms_schedule): Allow move-scheduling to add a new first stage.

	register substitutions here either.
	(apply_reg_moves): New function.
	(duplicate_insns_of_cycles): Use register indices directly,
	rather than finding instructions using PREV_INSN.  Use ps_reg_move.
	(sms_schedule): Call schedule_reg_moves before committing to
	a partial schedule.   Try the next ii if the schedule fails.
	Use apply_reg_moves instead of generate_reg_moves.  Adjust
	call to print_node_sched_params.  Free node_sched_param_vec
	instead of node_sched_params.

	PR libobjc/50428
	* sendmsg.c (__objc_send_initialize): If a class does not have an
	+initialize method, search for an +initialize method in the
	superclass and in the ancestor classes and execute the first one
	that is found.  This makes the GNU runtime behave in the same way
	as the Apple/NeXT runtime with respect to +initialize methods and
	subclassing.
