[Bug c++/21631] diagnostic for a non constant reference when passed a non lvalue (copy constructor)

Note T(T&) is still a copy constructor, just not one which takes a constant 
reference.
Also note:
it really bolls down to this testcase:
int  f(int&);
int f();
int g(void)
{
  return f(1);
}

If we get rid of the second f function, we get a good warning.
