  |     Split signed bitwise AND operations.
  |     
  |     The algorithm for bitwise AND struggles with complex signed operations
  |     which cross the signed/unsigned barrier.  When this happens, process it
  |     as 2 seperate ranges [LB, -1] and [0, UB], and combine the results.
  | ... 8 lines of the commit log omitted.
