; It features a SCEV value using %div44 for the inner loop (for.body.51 =>
; for.cond.60.preheader) that is computed within the body of the outer loop
; (for.cond.30.preheader => for.cond.60.preheader). CodeGenerator would add a
; computation of the SCEV to before the scop that references %div44, which is
; not available then.
