Accumulate Haddock comments in P (#17544, #17561, #8944)
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).
