Comment(by ehuelsmann):

 The change has been implemented for the instance creation and instance
 reinitialization cases in r13219 and r13220.

 I'm not sure we need the other two cases at all; presumably, UPDATE-
 INSTANCE-FOR-REDEFINED-CLASS will be called only a limited number of
 times: the exact number of live instances when the class is redefined.

 UPDATE-INSTANCE-FOR-DIFFERENT-CLASS will be called through CHANGE-CLASS,
 which can be any number of times, but is much more complex to cache, since
 multiple dispatch arguments are available. [the currently available
 infrastructure doesn't work with more than 1 specializing argument.]

 The commits do leave some room for finer cache granularity.
