Change creation of new internal classes

So far we often began with the empty class again when creating
new internal classes. This allowed for multiple paths through the
internal class hierarchy ending up at the same internal class object.

But to be able to efficiently garbage collect internal classes, we
need to have only one path to each instance of an internal class.
