The final batch of changes for the new coercion representation

* Fix bugs in the packing and unpacking of data
  constructors with equality predicates in their types

* Remove PredCo altogether; instead, coercions between predicated
  types (like  (Eq a, [a]~b) => blah) are treated as if they
  were precisely their underlying representation type
       Eq a -> ((~) [a] b) -> blah
  in this case

* Similarly, Type.coreView no longer treats equality
  predciates specially.

* Implement the cast-of-coercion optimisation in
  Simplify.simplCoercionF
