Log message:
	* basic-block.c (tail_recursion_label_list): Don't declare.

	accordingly.
	* cfgbuild.c (find_label_refs): Remove.
	(find_basic_blocks_1): Don't handle CALL_PLACEHOLDER insns.
	* cfgcleanup.c (tail_recursion_label_p): Remove.
	(merge_blocks_move): Do not check for tail recursion.
	(try_optimize_cfg): Likewise.
	(cleanup_cfg): Never handle CLEANUP_PRE_SIBCALL.
	* cfgrtl.c (tail_recursion_label_list): Remove.
	* except.c (remove_unreachable_regions): Don't handle
	CALL_PLACEHOLDER insns.
	(convert_from_eh_region_ranges_1, can_throw_internal,
	can_throw_external): Likewise.
	* function.c (free_after_compilation): Don't clear
	x_tail_recursion_label.
	(fixup_var_refs_insns): Don't handle CALL_PLACEHOLDER insns.
	(identify_blocks_1): Don't recurse for CALL_PLACEHOLDER insns.
	(reorder_blocks_1): Likewise.
	* function.h (struct function): Remove x_tail_recursion_label
	member.  Don't define tail_recursion_label.
	* jump.c (mark_all_labels): Don't handle CALL_PLACEHOLDER insns.
	* print-rtl.c (print_rtx): Likewise.
	* rtl.def (CALL_PLACEHOLDER): Remove.
	* rtl.h (sibcall_use_t): Remove enum.
	(optimize_sibling_and_tail_recursive_calls,
	replace_call_placeholder): Remove function prototypes.
	* stmt.c (tail_recursion_args): Remove.
