Fix crash when modifying objects used as prototypes
Changing the prototype of an object back and forth leads to a 'cyclic' reference in the internal class transition tables. If one of those objects then gets a new property, we would get an infinite stack recursion trying to update the internal class IDs of the classes using this prototype. Fixed by skipping protochanges and vtable changes in the update code. That's ok, as those classes will always be reached through other paths from the empty class.
