garbage collect InternalClass

Internal classes are now allocated and collected through
the GC. As they are important to the deletion of other
objects (because of the vtable pointer living inside the
internal class), they need to get destroyed after regular
objects have been sweeped. Achieve this by using a separate
block allocator for internal class objects.

Our lookups do often contain pointers to internal classes,
so those need to be marked as well, so we don't accidentally
collect them.
