[Jon Coppeard (:jonco)]

I needed a WeakMap whose value type was a struct containing GC pointers (or a UniquePtr to one). So this doesn't work for that, although it may be useful for other things.

I'm just going to drop this bug for now. I might look into making traceable non-GC things work as weakmap values after I finish cleanup on the gcWeakKeys rearchitecture.
