--- Comment #2 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Started with r14-2170-g4cf64d9cc2faf4, which means 

template <typename _Tp, typename _Up>
  struct is_same { static constexpr bool value = __is_same(_Tp, _Up); };

template <typename _Tp>
  using _Vp [[gnu::vector_size(16)]] = _Tp;

template <typename _Tp>
  struct Test
  {
    static_assert(not is_same<_Tp, _Vp<_Tp>>::value);
  };

Test<float> x;
