Move the internalClass field from Heap::Object to Heap::Base

And do not store the vtable in Heap::Base anymore. This change
makes the internal class the main distinguishing feature
of all garbage collected objects.

It also saves one pointer on all Objects. No measurable
impact on runtime performance.
