        sim: Add support for serializing BitUnionXX

        BitUnion instances can normally not be used with the SERIALIZE_SCALAR
        and UNSERIALIZE_SCALAR macros due to the way they are converted
        between their storage type and their actual type. This changeset adds
        a set of parm(In|Out) functions specifically for gem5 bit unions to
        work around the issue.
