dwarfout.c (byte_size_attribute): Add local var upper_bound and add case to handle STRING_TYPE.

        * dwarfout.c (byte_size_attribute):  Add local var upper_bound
        and add case to handle STRING_TYPE.
        * dwarfout.c (output_string_type_die):  Fix code to generate
        correct string length attribute for fixed length strings.
        Still needs support for varying length strings.
