Names appearing in Haddock docstrings are lexed and renamed like any other names
appearing in the AST. We currently rename names irrespective of the namespace,
so both type and constructor names corresponding to an identifier will appear in
the docstring. Haddock will select a given name as the link destination based on
its own heuristics.
This patch also restricts the limitation of `-haddock` being incompatible with
`Opt_KeepRawTokenStream`.
The export and documenation structure is now computed in GHC and serialised in
.hi files. This can be used by haddock to directly generate doc pages without
reparsing or renaming the source. At the moment the operation of haddock
is not modified, that's left to a future patch.
Updates the haddock submodule with the minimum changes needed.

Haddock comments are, first and foremost, comments. It's very annoying
to incorporate them into the grammar. We can take advantage of an
important property: adding a Haddock comment does not change the parse
tree in any way other than wrapping some nodes in HsDocTy and the like
(and if it does, that's a bug).
This patch implements the following:
* Accumulate Haddock comments with their locations in the P monad.
This is handled in the lexer.
* After parsing, do a pass over the AST to associate Haddock comments
with AST nodes using location info.
* Report the leftover comments to the user as a warning (-Winvalid-haddock).

Fixes #10398 in a different way, thereby also fixing #11579.
I inverted the logic of the Bool argument to "worker", to hopefully make
it more self-explanatory.
