For libgcj, RawData is preferred.
For Classpath, I don't think there is a standard.  In some cases,
like the AWT peers, the pointers are stored in a lookaside hash table
(which has a number of problems...).

One idea would be to use long and then change that to RawData in
libgcj and mark it appropriately ("// GCJ LOCAL: explanation") so
that we don't merge it by accident.
