the case of a DIE that has both DW_AT_specification and
DW_AT_abstract_origin set. That is, DW_AT_abstract_origin is set,
and the origin has DW_AT_specification set. This is basically a
clone of a function that implements an interface (this happens for
destructors, for instance). In this case, really do the cloning
of the interface implementation. If the cloned function happens
to be member function, use finish_member_function_reading to read
the properties relevant to its method-ness.
