[PATCH 2/9] ENABLE_CHECKING refactoring: libcpp
        * include/line-map.h: Use CHECKING_P instead of ENABLE_CHECKING.
        * init.c: Likewise.
        * macro.c (struct macro_arg_token_iter, set_arg_token,
        macro_arg_token_iter_init, macro_arg_token_iter_forward,
        macro_arg_token_iter_get_token, macro_arg_token_iter_get_location,
        alloc_expanded_arg_mem, _cpp_backup_tokens): Likewise.
