void createEntry(int hash, K key, V value, int bucketIndex) {
        Entry<K, V> e = table[bucketIndex];
        table[bucketIndex] = new Entry<K, V>(hash, key, value, e);

Like addEntry except that this version is used when creating entries as
part of Map construction or "pseudo-construction" (cloning,
deserialization). This version needn't worry about resizing the table.

Subclass overrides this to alter the behavior of SafelyHashMap(Map),
clone, and readObject.
