More work on diagnosing abstract classes. We can now handle cases like

class C {
  void g(C c);

  virtual void f() = 0;
};

In this case, C is not known to be abstract when doing semantic analysis on g. This is done by recursively traversing the abstract class and checking the types of member functions.
