RFR (XS): 8151988: Fix for bug - Hotspot deoptimizes div/mod pair usage

[dean.long at oracle.com]

How about this?  I think it gives the same result, but with fewer tests

              if (use->in(j) != in(j) &&(j != 0 || (use->in(j) != NULL && in(j) != NULL)) {
                break;
              }
