  Log Message:
  -----------
  [NARY] Don't optimize min/max if there are side uses (part2)

Previous attempt to fix infinite recursion in min/max reassociation was not fully successful (D100170). Newly discovered failing case is due to not properly handled when there is a single use. It should be processed separately from 2 uses case.
