    A bit of refactoring to TcErrors
    
    This replaces a bunch of boolean flags in ReportErrCtxt with
    an algebraic data type to say how to handle expression holes
    and type holes
    
    No change in functionality; I just found myself unable to understand
    the code easily, when thinking about something else.  Result is
    quite nice, I think.
