  EPA: Uses Parsers.parseModule for exactprint tests
  
  Parsers.parseModule is the advertised way to parse for use for exact
  printing in the ghc-exactprint library. This commit updates the GHC
  exact print testing to use it.
  
  This requires moving the comment balancing that was occurring
  only in the test path into the advertising parser path, so it moves
  from Transforms.hs to Utils.hs.
  
  Also update the comment adding to honour trailing annotations
