cygming-crtend.c (register_frame_ctor): If DEFAULT_USE_CXA_ATEXIT, register __gcc_deregister_frame directly with atexit.

	* config/i386/cygming-crtend.c (register_frame_ctor): If
	DEFAULT_USE_CXA_ATEXIT, register __gcc_deregister_frame
	directly with atexit.
	(deregister_frame_ctor): Rename to ...
	(deregister_frame_dtor): Use to call __gcc_deregister_frame
	if !DEFAULT_USE_CXA_ATEXIT.
