Add a bit-map encoding of Object-reference field offsets to ClassObject. Class.c populates a new field with a bit for each of the first 32 instance fields, to show if it is a reference or not, and an escape value if there is a reference field beyond 32. The GC uses the encoded bitmap -- if available -- to extract Object refererences from DataObjects.
