My goal is to remove the `object_pointer` member on `ParsedDWARFTypeAttributes` since it's duplicating information that we retrieve with `GetCXXObjectParameter` anyway. To continue having coverage for the `DW_AT_object_pointer` code-paths, instead of checking the `attrs.object_pointer` I'm now calling `GetCXXObjectParameter` directly. We could find some very roundabout way to go via the Clang AST to check that the object parameter was parsed correctly, but that quickly became quite painful. Depends on https://github.com/llvm/llvm-project/pull/144876
