    Improved the internal IntSet API and IntSet tests.
    
    * Changed internal functions lowTipBits and highTipBits to
      prefixOf, suffixOf and bitmapOf.
    
    * Use uncheckedShift[R]L# instead of Data.Bits.shift and
      Ghc.Exts shift[R]L# to achieve unchecked shifts.
    
    * Improve implementations if split, splitMember, minView, maxView.
    
    * Improved tests -- some properties and conditions were added.
