This patchset contains two useful methods for the Arc type. They will be
used in my Rust linked list implementation, which Rust Binder uses. See
the Rust Binder RFC [1] for more information. Both these commits and
the linked list that uses them are present in the branch referenced by
the RFC.

I will send the linked list to the mailing list soon.

This patchset is based on rust-next and depends on [2].
