	* target-insns.def (restore_stack_block, restore_stack_function)
	(restore_stack_nonlocal, save_stack_block, save_stack_function)
	(save_stack_nonlocal): New targetm instruction patterns.
	* builtins.c (expand_builtin_apply): Use them instead of
	HAVE_*/gen_* interface.
	* explow.c (emit_stack_save, emit_stack_restore): Likewise.
