FIX #2693
- As long as the first reduceContext in tcSimplifyRestricted potentially
  performs improvement, we need to zonk again before the second reduceContext.
  It would be better to prevent the improvement in the first place, but given
  the current situation zonking is definitely the right thing to do.

  MERGE TO 6.10
