* 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.
