For cases where the class has direct calls (that is, we cast `this` to the subclass before making the call) no longer declare Recv/Answer methods on the base class at all. This should ensure that slots for them are not generated in vtables, and also allow the derived class to choose the method signature (e.g. whether it wants to take something by reference or by value).
