--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
  gcc_checking_assert (T::includes_p (m));

So only ICEs with checking enabled.

The ICE comes from
      scalar_int_mode shift_unit_mode
        = as_a <scalar_int_mode> (GET_MODE_INNER (shift_mode));

So maybe caused by r8-2775-ge3731c52cf1b60 (or maybe it was there earlier than
that though).
