    Remember the AvailInfo for each IE
    
    This is another take on https://phabricator.haskell.org/D3844.
    
    This patch removes then need for haddock to reimplement the calculation
    of exported names from modules. Instead when renaming export lists ghc
    annotates each IE with its exported names.
    
    Haddocks current  export logic has caused lots of trouble in the past
    (on the Github issue tracker):
