    Checkpoint: generalize to support arbitrary built-in constructors.
    
    This is done by adding a new TyConRHS (cf TyCon).
    The operations for type-checking a built-in tycon are in FamInst.
    
    This is a checkpoint because the current build does not seem to work
    on my machine: for some reason things like (+) are considered to be Open.
    
    The reason could be that I need to rebuild more things or, perhaps the
    type nat tycons need to be introduced in a different way.  Currently,
    they are just declared as ordinary type families.
