[Lldb-commits] [lldb] Improve performance of .debug_names lookups when DW_IDX_parent attributes are used (PR #91808)

I think #77696 is justification enough to add this check, but I don't think we should be implicating DW_IDX_parent_entries until we know how those came about. Both me and David have tried to produce entries like you describe and failed (in fact I was not able to produce a DW_IDX_parent_entries referring to any kind of class type whatsoever (only to namespace entries)).

Even when this check goes in, I think it would be useful to get to the bottom of the DW_IDX_parent_entries issue, if nothing else, then because it may affect the decision of when/if to remove this workaround.
