[Bug c++/19569] New: no code for explicit instantiation of template class specialization

[jamesp at trdlnk dot com]

It appears that explicit instantiation of specialized template classes isn't
instantiating all of the class's members as it should:

--- Begin Sample Code ------------
template <typename T>
class A
{
public:
    void foo( T const & ) {}
};

template <>
class A<char>
{
public:
    void foo( char const & ) {}
};

template class A<int>;
template class A<char>;

--- End Sample Code ------------

When I compile the above code and run nm on the object file, I get:
%nm test.o
00000000 W _ZN1AIiE3fooERKi
%

The explicit instantiation of the char specialization of class A should have
created A<char>::foo(char const &).
