	(debug_dependencies): Likewise for both params.

	* haifa-sched.c (insn_delay): Likewise for param "insn".
	(real_insn_for_shadow): Likewise for return type and param "insn".
	(update_insn_after_change): Likewise for param "insn".
	(recompute_todo_spec): Likewise for param "next" and locals "pro",
	"other".
	(insn_cost): Likewise for param "insn".

	(model_reset_queue_indices): Likewise for local "insn".
	(unschedule_insns_until): Strengthen local "recompute_vec" from
	auto_vec<rtx> to auto_vec<rtx_insn *>.  Strengthen locals "last",
	"con" from rtx to rtx_insn *.
	(restore_last_backtrack_point): Likewise for both locals "x". Add
	checked casts.
	(estimate_insn_tick): Likewise for param "insn".

	local "x".
	(verify_shadows): Likewise for locals "i1", "i2".
	(dump_insn_stream): Likewise for params "head", "tail" and locals
	"next_tail", "insn".

	cast.
	(fix_inter_tick): Likewise for params "head", "tail".
	(create_check_block_twin): Likewise for local "jump".

	"tail" from rtx to rtx_insn *.
	* sched-rgn.c (void debug_dependencies): Likewise, also for locals
	"insn", "next_tail".
