Native functions now only get the Interpreter& as an argument. They can then extract |this| along with any indexed arguments it wants from it. This forces functions that want |this| to actually deal with calling interpreter.this_value().to_object(), and dealing with the possibility of a non-object |this|. This is still not great but let's keep massaging it forward.
