      Description

      Introduce ZRootsIteratorClosure to allow piggybacking per-thread operations when iterating over thread roots. Use this to update the thread local address bad mask, instead of having that logic buried inside the ZRootIterator, which should not have knowledge of this. This mechanism will later also be used to retire/resize/remap TLABs.
