[Bug c++/61732] Derivation from final class incorrectly allowed

Umm... This is not how I read [class]/3 (no mention to instances there). And,
moreover, if your interpretation was right then the following should compile
too:

struct X final{};

struct derived:X{};

void foo(derived*){}

int main()
{
  foo(0);
}

but GCC, here, does complain that derived can't derive from X.
