	* haifa-sched.c (schedule_insn): Return necessary cycle advance
	after issuing the insn.
	(rank_for_schedule): Make a insn with /S the highest priority
	insn.
	(move_insn): Ignore schedule groups.  Clear SCHED_GROUP_P.
	(choose_ready): Check SCHED_GROUP_P.
	(schedule_block): Advance cycle after issuing insn if it is
	necessary.  Don't reorder insns if there is an insn with /S.
	(set_priorities): Ignore schedule groups.

	* sched-deps.c (remove_dependence, group_leader): Remove the
	functions.
	(add_dependence): Ignore schedule groups.
	(set_sched_group_p): Don't make copy of dependencies from previous
	insn of the schedule group.  Add anti-dependency to the previous
	insn of the schedule group.
	(compute_forward_dependences): Ignore schedule groups.

	* sched-ebb.c (init_ready_list): Ignore schedule groups.

	* sched-rgn.c (init_ready_list): Ditto.
	(can_schedule_ready_p): Ditto.
