Patch that implements the __is_final intrinsic

I am attaching a patch that implements the __is_final() intrinsic function that
checks whether a class is declared final. In other words, the code:

struct A {};
struct B final {};

int main()
{
  std::cout << __is_final(A) << " " << __is_final(B) << "\n";
}

should output "0 1".

This intrinsic is motivated by the library bug #11461.
