  Log Message:
  -----------
  [SelectionDAG] Further improve computeKnownBits for (smax X, C) where C is non-negative.

Move the code that was added for D126896 after the normal recursive calls
to computeKnownBits. This allows us to calculate trailing zeros.
Previously we would break out of the switch before the recursive calls.
