Shu-yu Guo 93c0be4b7c [weakrefs] Make unregister_token undefined on popped WeakCells 
The unregister_token slot is iterated as a custom weak pointer slot,
which means the heap verifier treats it as a strong slot. Currently,
popped WeakCells (that is, WeakCells for which the owning
FinalizationRegistry's finalizer has already been invoked) neither
clears out the unregister_token slot nor marks it, which trips the heap
verifier.
