When we know that we are parsing a class-name, implicitly construct a
TypenameType if getTypeName is looking at a member of an unknown
specialization. This allows us to properly parse class templates that
derived from type that could only otherwise be described by a typename type,
e.g.,
template<class T> struct X {};
template<typename T> struct Y : public X<T>::X { };
Fixes PR4381.
