[Bug c++/18313] Missing warning for superfluous const's in return types

[bangerth at dealii dot org]

Hm, I'm not sure if I like this situation. Consider this snippet,
typical of template games:
---------------
  template <typename T> class Array {
    T& operator();
    T operator() const;
  };
---------------
This class will trigger a warning if instantiated as Array<const double>
because the return type of the second operator() is now 'const double'.
