The testcases fail (even when adding the flags mentioned before) due to the
decision to apply SMS when stage_count greater than 1.
If stage_count is 1 it means the new SMSed kernel includes instructions from a
single iteration of the original loop -- in that case SMS fails and leaves the
scheduling task to the scheduler. In r146278 SMS has been applied also when SC
equals 1 so the testcases passed with that version.
