sim: Add support for serializing BitUnionXX

Browse source 
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.
