    Use UniqDFM for HomePackageTable
    
    This isn't strictly necessary for deterministic ABIs.
    The results of eltsHpt are consumed in two ways:
    1) they determine the order of linking
    2) if you track the data flow all the family instances get put in
       FamInstEnvs, so the nondeterministic order is forgotten.
    3) same for VectInfo stuff
    4) same for Annotations
    
    The problem is that I haven't found a nice way to do 2. in
    a local way and 1. is nice to have if we went for deterministic
    object files. Besides these maps are keyed on ModuleNames so they
    should be small relative to other things and the overhead should
    be negligible.
    
    As a bonus we also get more specific names.
