Shu-yu Guo 45bb44985e [weakrefs] Hold unregister tokens weakly ... Change unregister tokens to be held weakly instead of strongly. This enables the use case for an object to be used as its own unregister token. To avoid using an ephemeron table, FinalizationGroup's key_map is changed to key off unregister tokens' identity hashes. Because hashes may collide, a single key list may rarely contain multiple tokens. When a FinalizationGroup WeakCell's token becomes unreachable, during GC, it is removed from the the doubly linked key list and removed from the key map if it had a unique key.
