	* toplev.c (backend_init): Don't emit line notes for
	unreachable code warnings.

	* combine.c (distribute_notes): Don't distribute a
	REG_VTABLE_REF note.

	* rtl.c (reg_note_name): Remove it.
	* rtl.h (enum reg_node): Dito.

	* emit-rtl.c (force_line_numbers, restore_line_number_status):
	Remove.
	* rtl.h (force_line_numbers, restore_line_number_status):
	Remove prototypes.

	* stmt.c (using_eh_for_cleanups_p, using_eh_for_cleanups): Move...
	* tree-eh.c (using_eh_for_cleanups_p): ...here.  Make static.
	(using_eh_for_cleanups): Also moved here.

	* expr.c (expand_expr_real_1) <CASE_LABEL_EXPR>: Die if we see one.
	<SWITCH_EXPR>: Die if we have a non-NULL SWITCH_BODY.  Update calls
	to expand_start_case and add_case_node.
	* stmt.c (struct nesting): Cleanup unused fields condition_code,
	last_unconditional_cleanup, nominal_type, printname, and
	line_number_status.

	pushcase, pushcase_range): Remove.
	(expand_start_bindings_and_block): Don't set unused fields in
	the nesting stack.
	(expand_start_case, add_case_node): Cleanup unused formal arguments.
	(expand_end_case_type): Don't simplify the case-list.  Use emit_jump
	instead of emit_jump_if_reachable.
	(emit_case_nodes): Likewise.
	* tree-cfg.c (group_case_labels, cleanup_dead_labels): No longer
	static.
	(update_eh_label): Work around left-over exception handing regions.
	* tree-flow.h (group_case_labels, cleanup_dead_labels): Add protos.
	* tree-optimize.c (execute_cleanup_cfg_post_optimizing): New function.
	(pass_cleanup_cfg_post_optimizing): New pass.
	(init_tree_optimization_passes): Run the new pass after all
	optimizations.
