[via cfe-commits]

The code change looks nice. However you still need to update the documentations.

more specifically:
- Edit `fuchsia/multiple-inheritance.rst`
- Create a new doc for `misc/multiple-inheritance.rst`
- Modify `list.rst` for correct aliasing
- Document the change in `clang-tools-extra/docs/ReleaseNotes.rst`
