This is a follow-on to the itable factorization 6812831.  This work, and any similar work, generally changes the size of vtable and/or itable stubs, which requires a delicate manual update to the constants that allocate those stubs.

The vtable & itable stub code needs more documentation and asserts, so that errors in the size constants can be detected immediately.
