I don't think we have any assumptions about the number of fields of
Object.  Or if we do they must be parameterized, since this can
already change depending on hash synchronization.

I do know we have assumptions about the layout of vtables and the
ordering of virtual methods in Object.  In particular we assume that
finalize is the first method.
