Port Haddock to use the GHC API

[simonmar@…]

 Haddock currently uses its own Haskell parser. It lacks supports for some GHC extensions, and it requires its own implementation of the Haskell module system, has its own format for interface files, and so on. It can't produce documentation for functions that have no type signatures, because it has no type system and can't infer the types.

If Haddock were built on top of the new GHC API, these shortcomings would be fixed, and Haddock would get a lot shorter (although the binary might be larger :-). GHC's parser would need to be adapted to handle Haddock-style documentation annotations, and the abstract syntax would have to carry these around.
