[Bug c++/25666] New: Bad diagnostic for templated destructor as friend

[reichelt at gcc dot gnu dot org]

This is a spin-off for the diagnostic issue from PR 25638:

=========================================
struct A { ~A(); };

struct B
{
    template<int> friend A::~A();
};
=========================================

For the above code we get the error message:

  bug.cc:5: error: prototype for 'A::~A()' does not match any in class 'A'
  bug.cc:1: error: candidate is: A::~A()

The error message could be better:
1) A destructor can never be a template. This is not mentioned yet.
2) We only print 'A::~A()' as the prototype. We should probably print
   that we have a template here. Otherwise there's no difference to the
   rejected candidate.
