      Add a new isSignWrappedSet() method to ConstantRange. · a35462da
      Nick Lewycky authored
      Fix zeroExtend and signExtend to support empty sets, and to return the smallest
      possible result set which contains the extension of each element in their
      inputs. For example zext i8 [100, 10) to i16 is now [0, 256), not i16 [100, 10)
      which contains 63446 members.

       - remove ashr which never worked.
       - fix lshr and shl and add tests.
       - remove dead function "intersect1Wrapped".
       - add a new sub method to subtract ranges, with test.
