(simplify

 (if (INTEGRAL_TYPE (type)
      && types_match (TREE_TYPE (@0), TREE_TYPE (@1))
      && element_precision (TREE_TYPE (@0)) < element_precision (type))
 (with { type ntype =3D find_next_best_type (TREE_TYPE (@0));
  }
  (if (ntype

       && element_precision (ntype) < element_precision (type))
   (convert (plus (convert:ntype @0) (convert:ntype @1)))
  )

Where find_next_best_type checks int, long, long long types ...=
