- Add tagptr crate to the dependencies. - Remove `region: CacheRegion` field from `DeqNode`. - Change the pointer type used in `access_order_q_node` field of `DeqNodes` from `NonNull<DeqNode<T>>` to `TagNonNull<DeqNome<T>, 2>`, and embed `CacheRegion` value into the 2-bit tag space in the `TagNonNull` pointer. - Update the methods in `Deques` to handle the `TagNonNull` pointers.
