I've phrased the discussion in terms of fields first, since those are
simpler. It may make sense to have a combine type/name/code array.
(We may want a separate per-class array for static fields, with the
pointer fields (except for RawData) first, for the sake of GC.)

My job is hand-waving; the hard stuff I leave to you ..
Seriously, I'm sketching out an idea, but it clearly needs quite
a bit more detail work.
