modulo-sched.c (ps_insn): Adjust comment.

gcc/
	* modulo-sched.c (ps_insn): Adjust comment.
	(ps_reg_move_info): New structure.
	(partial_schedule): Add reg_moves field.
	(SCHED_PARAMS): Use node_sched_param_vec instead of node_sched_params.
	(node_sched_params): Turn first_reg_move into an identifier.
	(ps_reg_move): New function.
	(ps_rtl_insn): Cope with register moves.
	(ps_first_note): Adjust comment and assert that the instruction
	isn't a register move.
	(node_sched_params): Replace with...
	(node_sched_param_vec): ...this vector.
	(set_node_sched_params): Adjust accordingly.
	(print_node_sched_params): Take a partial schedule instead of a ddg.
	Use ps_rtl_insn and ps_reg_move.
	(generate_reg_moves): Rename to...
	(schedule_reg_moves): ...this.  Remove rescan parameter.  Record each
	move in the partial schedule, but don't emit it here.  Don't perform
	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.
	(create_partial_schedule): Initialize reg_moves.
	(free_partial_schedule): Free reg_moves.
