cfgrtl.c: Use rtx subclasses

gcc/
2014-08-21  David Malcolm  <dmalcolm@redhat.com>

	* cfgrtl.c (can_delete_note_p): Require a const rtx_note * rather
	than a const_rtx.
	(can_delete_label_p): Require a const rtx_code_label * rather than
	a const_rtx.
	(delete_insn): Add checked cast to rtx_code_label * when we know
	we're dealing with LABEL_P (insn).  Strengthen local "bb_note" from
	rtx to rtx_insn *.
	(delete_insn_chain): Strengthen locals "prev" and "current" from
	rtx to rtx_insn *.  Add a checked cast when assigning from
	"finish" (strengthening the params will come later).  Add a
	checked cast to rtx_note * in region where we know
	NOTE_P (current).
	(rtl_delete_block): Strengthen locals "insn" and "end" from rtx to
	rtx_insn *.
	(compute_bb_for_insn): Likewise.
	(free_bb_for_insn): Likewise for local "insn".
	(compute_bb_for_insn): Likewise.
	(update_bb_for_insn_chain): Strengthen params "begin", "end" and
	local "insn" from rtx to rtx_insn *
	(flow_active_insn_p): Require a const rtx_insn * rather than a
	const_rtx.
	(contains_no_active_insn_p): Strengthen local "insn" from rtx to
	rtx_insn *.
	(can_fallthru): Likewise for locals "insn" and "insn2".
	(bb_note): Likewise for local "note".
	(first_insn_after_basic_block_note): Likewise for local "note" and
	for return type.
	(rtl_split_block): Likewise for locals "insn" and "next".
	(unique_locus_on_edge_between_p): Likewise for locals "insn" and
	"end".
	(rtl_merge_blocks): Likewise for locals "b_head", "b_end",
	"a_end", "del_first", "del_last", "b_debug_start", "b_debug_end",
	"prev", "tmp".
	(try_redirect_by_replacing_jump): Likewise for locals "insn" (both of
	them), "kill_from", "barrier", "new_insn".
	(patch_jump_insn): Likewise for params "insn", "old_label".
	(redirect_branch_edge): Likewise for locals "old_label", "insn".
	(force_nonfallthru_and_redirect): Likewise for locals "insn",
	"old_label", "new_label".
	(rtl_tidy_fallthru_edge): Likewise for local "q".
	(rtl_split_edge): Likewise for locals "before", "last".
	(commit_one_edge_insertion): Likewise for locals "before",
	"after", "insns", "tmp", "last", adding a checked cast where
	currently necessary.
	(commit_edge_insertions): Likewise.
	(rtl_dump_bb): Likewise for locals "insn", "last".
	(print_rtl_with_bb): Likewise for local "x".

	(purge_dead_edges): Likewise for local "insn".
	(fixup_abnormal_edges): Likewise for locals "insn", "stop", "next".
	(skip_insns_after_block): Likewise for return type and for locals
	"insn", "last_insn", "next_head", "prev".
	(record_effective_endpoints): Likewise for locals "next_insn",
	"insn", "end".
	(fixup_reorder_chain): Likewise for locals "bb_end_insn" and "end".
	(verify_insn_chain): Likewise for locals "x", "prevx", "nextx".
	(cfg_layout_can_duplicate_bb_p): Likewise for local "insn".
	(duplicate_insn_chain): For now, add checked cast from rtx to
	rtx_insn * when returning insn.
