This fix looks "obviously" correct.  Consider it approved.

My goof for not knowing this during review.  Indeed this change was

on Kaveh's side that perhaps the Java front-end should consider
defining additional "C" types to assist the middle-end in performing
this type of builtin optimization/transformation.
