Don't inject the class name until that magical lbrace.
Because of the rules of base-class lookup* and the restrictions on typedefs, it
was actually impossible for this to cause any problems more serious than the
spurious acceptance of
template <class T> class A : B<A> { ... };
instead of
template <class T> class A : B<A<T> > { ... };

is well worth making another Parser->Sema call for.

Clang reasonably adds all the base specifiers in one pass; this is now required
