 Make unique auxiliary function names in deriving

 In deriving for Data, we make some auxiliary functions, but they
 didn't always get distinct names (Trac #12245).  This patch fixes
 it by using the same mechanism as for dictionary functions, namely
 chooseUniqueOccTc.

 Some assocated refactoring came along for the ride.
