    Clarify what is in ic_tythings, and refactor TcRnDriver.setInteractiveContext
    
    Previously there was a ton of cruft to do wtih "visible ids" in
    setInteractiveContext, but I made it all a lot simpler by providing
    a way to add to the typecheckers list of "global type variables",
    via TcEnv.tcExtendGlobalTyVars.  This is much nicer.
