--- Comment #3 from Drea Pinski <pinskia at gcc dot gnu.org> ---
For the reduced testcase we can optimize it better:
  vect__1.10_32 = MEM <vector(4) int> [(int *)&a];
  mask__7.11_33 = vect__1.10_32 != { 0, 0, 0, 0 };
  mask__8.12_34 = mask__7.11_33 & { -1, 0, 0, 0 };
  if (mask__8.12_34 != { 0, 0, 0, 0 })

That should just be
_22 = MEM <int> [(int *)&a]
  if (_22 != 0)
