	struct toklist_dummy): New.
	(cpp_free_definition): Free macros with free_macro.
	(count_params): Don't save paramter spellings.  Save macro
	information in a struct macro_info.
	(parse_define): Don't allocate a token list.
	(save_expansion): Allocate the macro's token list, and
	save parameter spellings if necessary.  Use TOKEN_SPELL.
	(cpp_create_definition): Make list const.
