DW_AT_data_member_location only stores the offset without the name now

[s22chan]

This change occurs when moving from the OSX 10.9 SDK -> 10.15 SDK..

ex:

{'fields': {'DW_AT_name': 'member_name', 'DW_AT_type': '0x000002fa "class_name"', 'DW_AT_decl_file': 'src/test.h', 'DW_AT_decl_line': '364', 'DW_AT_data_member_location': '0x00'}, 'tag': 'DW_TAG_member', 'addr': '0x000000b2', 'has_children': False}
