This adds a new slot to the type that can provide a custom traversal for handling immutable/freezing of the code. Currently if this is not provided it falls back to tp_traverse.
This removes a special case from the code.

The addition itself looks good, but it doesn't set the tp_reachable for most built-in types. Once that is done it should be good to go.
