 Remove dead generics-related code from OccName

 Before #9766 was fixed, GHC would generate auxiliary datatypes for every
 Generic instance, and it would use functions from OccName to prefix the
 generated names. GHC no longer generates any auxiliary datatypes for
 Generic instances, but the accompanying code was never removed from
 OccName (until now).
