list for attributes that don't have the loclist class. Summary: The overflow error occurs when we try to dump location list for those attributes that do not have the loclist class, like DW_AT_count and DW_AT_byte_size. After re-reviewed the entire list, I sorted those attributes into two parts, one for dumping location list and one for dumping the location expression.
