c3f14d55e8 re PR bootstrap/62304 (ICE in follow_jumps, find_dead_or_set_registers)
PR bootstrap/62304

	* gcc/reorg.c (skip_consecutive_labels): Convert return type and
	param back from rtx_insn * to rtx.  Rename param from "label" to
	"label_or_return", reintroducing "label" as an rtx_insn * after
	we've ensured it's not a RETURN.
	(first_active_target_insn): Likewise for return type and param;
	add a checked cast to rtx_insn * once we've ensured "insn" is not
	a RETURN.
	(steal_delay_list_from_target): Convert param "pnew_thread" back
	from rtx_insn ** to rtx *.  Replace use of JUMP_LABEL_AS_INSN
	with JUMP_LABEL.
	(own_thread_p): Convert param "thread" back from an rtx_insn * to
	an rtx.  Introduce local rtx_insn * "thread_insn" with a checked
	cast once we've established we're not dealing with a RETURN,
	renaming subsequent uses of "thread" to "thread_insn".
	(fill_simple_delay_slots): Convert uses of JUMP_LABEL_AS_INSN back
	to JUMP_LABEL.
	(follow_jumps): Convert return type and param "label" from
	rtx_insn * back to rtx.  Move initialization of "value" to after
	the handling for ANY_RETURN_P, adding a checked cast there to
	rtx_insn *.  Convert local rtx_insn * "this_label" to an rtx and
	rename to "this_label_or_return", reintroducing "this_label" as
	an rtx_insn * once we've handled the case where it could be an
	ANY_RETURN_P.
	(fill_slots_from_thread): Rename param "thread" to
	"thread_or_return", converting from an rtx_insn * back to an rtx.
	Reintroduce name "thread" as an rtx_insn * local with a checked
	cast once we've handled the case of it being an ANY_RETURN_P.
	Convert local "new_thread" from an rtx_insn * back to an rtx.
	Add a checked cast when assigning to "trial" from "new_thread".
	Convert use of JUMP_LABEL_AS_INSN back to JUMP_LABEL.  Add a
	checked cast to rtx_insn * from "new_thread" when invoking
	get_label_before.
	(fill_eager_delay_slots): Convert locals "target_label",
	"insn_at_target" from rtx_insn * back to rtx.
	Convert uses of JUMP_LABEL_AS_INSN back to JUMP_LABEL.
	(relax_delay_slots): Convert locals "trial", "target_label" from
	rtx_insn * back to rtx.  Convert uses of JUMP_LABEL_AS_INSN back
	to JUMP_LABEL.  Add a checked cast to rtx_insn * on "trial" when
	invoking update_block.
	(dbr_schedule): Convert use of JUMP_LABEL_AS_INSN back to
	JUMP_LABEL; this removes all JUMP_LABEL_AS_INSN from reorg.c.

	* resource.h (mark_target_live_regs): Undo erroneous conversion
	of second param of r214693, converting it back from rtx_insn * to
	rtx, since it could be a RETURN.

	* resource.c (find_dead_or_set_registers): Similarly, convert
	param "jump_target" back from an rtx_insn ** to an rtx *, as we
	could be writing back a RETURN.  Rename local rtx_insn * "next" to
	"next_insn", and introduce "lab_or_return" as a local rtx,
	handling the case where JUMP_LABEL (this_jump_insn) is a RETURN.
	(mark_target_live_regs): Undo erroneous conversion
	of second param of r214693, converting it back from rtx_insn * to
	rtx, since it could be a RETURN.  Rename it from "target" to
	"target_maybe_return", reintroducing the name "target" as a local
	rtx_insn * with a checked cast, after we've handled the case of
	ANY_RETURN_P.

	rtx_insn_list for clarity and typesafety.
	(add_to_delay_list): Strengthen return type and param "insn" from
	rtx to rtx_insn *.  Strengthen param "delay_list" from rtx to
	rtx_insn_list * and use methods of rtx_insn_list.
	(delete_from_delay_slot): Strengthen return type, param "insn",
	locals "trial", "seq_insn", "prev" from rtx to rtx_insn *.
	Strengthen local "seq" from rtx to rtx_sequence *, and local
	"delay_list" from rtx to rtx_insn_list *, using methods of
	rtx_sequence for clarity and type-safety.
	(delete_scheduled_jump): Add checked cast when invoking
	delete_from_delay_slot.  Strengthen local "trial" from rtx to
	rtx_insn *.
	(optimize_skip): Strengthen return type and local "delay_list"
	from rtx to rtx_insn_list *.  Strengthen local "trial" from rtx to
	rtx_insn *.

	"delay_list" and local "new_delay_list" from rtx to
	rtx_insn_list *.  Strengthen param "seq" from rtx to
	rtx_sequence *.  Strengthen param "pnew_thread" from rtx * to
	rtx_insn **.
	Split out local "temp" into multiple more-tightly scoped locals:
	sometimes an rtx_insn_list *, and once a rtx_insn *.  Use methods
	of rtx_insn_list and rtx_sequence for clarity and typesafety.
	Strengthen locals named "trial" from rtx to rtx_insn *.
	(steal_delay_list_from_fallthrough): Strengthen return type and
	param "delay_list" from rtx to rtx_insn_list *.  Strengthen param
	"seq" from rtx to rtx_sequence *.  Use methods of rtx_sequence.
	Strengthen local "trial" from rtx to rtx_insn *.
	(try_merge_delay_insns): Strength local "merged_insns" from rtx
	to rtx_insn_list * and use its methods.  Strengthen local "pat"
	from rtx to rtx_sequence * and use its methods.  Strengthen locals
	"dtrial" and "new_rtx" from rtx to rtx_insn *.
	(get_label_before): Strengthen return type and local "label" from
	rtx to rtx_insn *.
	(fill_simple_delay_slots): Likewise for locals "insn", "trial",
	"next_trial", "next", prev".  Strengthen local "delay_list" from
	rtx to rtx_insn_list *  Strengthen local "tmp" from rtx * to

	"insn", "next", "value", "this_label" from rtx to rtx_insn *.
	(fill_slots_from_thread): Strengthen return type, param
	"delay_list" from rtx to rtx_insn_list *.  Strengthen params
	"insn", "thread", "opposite_thread" and locals "new_thread",
	"trial", "temp", "ninsn" from rtx to rtx_insn *.  Introduce local
	"sequence" from a checked cast to rtx_sequence so that we can call
	steal_delay_list_from_target and steal_delay_list_from_fallthrough
	with an rtx_sequence *.
	(fill_eager_delay_slots): Strengthen locals "insn", "target_label",
	"insn_at_target", "fallthrough_insn" from rtx to rtx_insn *.
	Strengthen local "delay_list" from rtx to rtx_insn_list *.
