    Kill redundant import
    
    I don't really understand this.  GHC.hs had:
    
      module GHC( ...,  module HsSyn, ... ) where
        import HsSyn
        import qualified HsSyn -- hack as we want to reexport the whole module
    
    GHC now reports the 'import qualified' line as redundant; and it certainly
    is, because 'import HsSyn' brings everything into scope qualified *and*
    unqualified.   I have no idea why the "hack" was necessary before, but
    following my refactoring of tcg_used_gres (previous commit), it's reported
    as redundant, so I've deleted it.
    
    I'm making it a separate commit because it seems a bit mysterious and I
    wanted to draw attention to it.
