Actually, the current approach should take care of that already; we call `DWARFDebugInfoEntry::GetName`, whose implementation is:

```
const char *DWARFDebugInfoEntry::GetName(const DWARFUnit *cu) const {
  return GetAttributeValueAsString(cu, DW_AT_name, nullptr, true);
}
```

This is going to look through AT_specification and AT_abstract_origin.

I should still add a  test to verify this though!
