Yes, I'll remove those: you're now supposed to use:
	mono_object_get_domain (obj)
	mono_object_get_class (obj)

That is a pathological case of the debugger accessing data it should not
access. Martin committed a fix already, I'll move the function to the
debugger headers so people won't use it.
The only interesting data users may want to know about MonoVTable is
domain and klass, but they already have access to that info since they
either created the vtable themselves from a domain and a klass, or
they got the vtable from an object and they can use the above functions
to get the info from the object itself.
