    Refactor TyCon to eliminate TupleTyCon
    
    This makes TupleTyCon into an ordinary AlgTyCon, distinguished
    by its AlgTyConRhs, rather than a separate constructor of TyCon.
    
    It is preparatory work for making constraint tuples into classes,
    for which the ConstraintTuple tuples will have a TyConParent
    of a ClassTyCon.  Tuples didn't have this possiblity before.
    
    The patch affects other modules because I eliminated the
    unsatisfactory partial functions tupleTyConBoxity and tupleTyConSort.
    And tupleTyConArity which is just tyConArity.
