Comment (by simonmar):

 @archblob asked me about this on IRC.  I suggested that rather than making
 `ifName` a qualified name, it would be better to pass in the `Name` when
 pretty printing the `IfaceDecl`.  There's only one `ifName` per
 `IfaceDecl`, so passing it in separately should be fine.

 I wonder about things like constructor names (`ifConOcc`), record field
 names (`ifConFields`), and method names though.  Perhaps they need to be
 qualified too.  In which case you'll need to pass in more `Name`s for
 those.

 Another thought I had is that perhaps it would be better to reify the
 stuff into `THSyn` and print that instead.  `THSyn` is closer to Haskell
 than `IfaceSyn`.  But perhaps that would mean duplicating the tidying
 logic?
