Permit a class to friend its class members in C++ 98, as long as extensions
are enabled (and even when they aren't, only give an extwarn about it).

we were going to enter into the scope of a class template or class
template partial specialization, rebuild that type so that it can
refer to members of the current instantiation, as in code like

  template<typename T>
  struct X {
    typedef T* pointer;
    pointer data();
  };

  template<typename T>
  typename X<T>::pointer X<T>::data() { ... }

Without rebuilding the return type of this out-of-line definition, the
canonical return type of the out-of-line definition (a TypenameType)
will not match the canonical return type of the declaration (the
canonical type of T*).

transform, then use the result for template instantiation. The generic
transformation fixes a few issues:

  - It copes better with template template parameters and member
  templates (when they're implemented). 
  - The logic used to replace template template parameters with their
  arguments is now centralized in TransformDecl, so that it will apply
  for other declaration-instantiation steps.
  - The error-recovery strategy is normalized now, so that any error
  results in a NULL TemplateName.
