by marcus.denkerremove methods:
the (quite complex) logic in #updateInstancesFrom: and
updateInstances:from:isMeta: has been taken over by the class builder
(and takes into account user defined instance variables).
I think we should delete these methods: they are not part of the public
API
fixes #3550
