/* There should be no loops generated for this testcase, instead we
   should generate the following:

   | if (winner >= 0 && winner < numf2s && Y[winner].y > 0)

   For the moment this is XFAILed as this loop is not detected as a
   SCoP by graphite: we depend on data in one of the conditions,
   "Y[winner].y > 0".  This could be fixed when we will use predicates
   for such cases.  */
