 Add more type class instances for GHC.Generics

 GHC.Generics provides several representation data types that have
 obvious instances of various type classes in base, along with various
 other types of meta-data (such as associativity and fixity).
 Specifically, instances have been added for the following type classes
 (where possible):

     - Applicative
     - Data
     - Functor
     - Monad
     - MonadFix
     - MonadPlus
     - MonadZip
     - Foldable
     - Traversable
     - Enum
     - Bounded
     - Ix
     - Generic1

 Thanks to ocharles for starting this!
