Before this CL, if initializing from a dill file containing a class,
say A, but it wasn't used, and then later using it as a type, say
'A a = new A()', the class hierarchy would complain about not knowing A.
This was caused by the class hierarchy initially being constructed using
the full component of the first compile (i.e. in the example above
without any usage of A and thus without including A), and subsequent
compiles telling the class hierarchy about new classes created in that
compile. The problem was, that if the class was loaded from a dill file
(in the example above 'A' was such a class) it would never be included
if not a part of the first full component.
This CL fixes it by changing the interface to the class hierarchys
`applyTreeChanges` function and letting the class hierarchy know about
libraries too: It will now basically just be given the full component
when asked to update, and just update with the libraries it doesn't
already know about. In the example above that would - once using 'A' -
include 'A'.
