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.
