Reimplement registerDisposable in term of on-dispose callback.

Presumably, unless you're creating and disposing object in hot loop
(if you do that, you should probably fix that anyway),
slight loss in performance should not matter (I'm not even sure this
will actually be slower, given that goog.disposeAll creates an
arguments object).
