Compile speed improvement.

	* parser.c (cp_lexer_print_token): Only define if ENABLE_CHECKING set.
	Otherwise define a stub macro that expands to nothing.
	(cp_lexer_debugging_p): Only define if ENABLE_CHECKING set.  Otherwise
	define a stub macro that expands to 0.
	(cp_lexer_start_debugging): Only define if ENABLE_CHECKING set.
	(cp_lexer_stop_debugging): Likewise.
	(cp_lexer_debug_stream): Only define if ENABLE_CHECKING set.  Otherwise
	define a stub macro that expands to NULL.
	(cp_lexer_new_main): Only set debugging_p if ENABLE_CHECKING set.
	(cp_lexer_new_from_tokens): Likewise.
