Log Message:
-----------
CogVM source as per VMMaker.oscog-eem.915
Spur: Fix processWeakSurvivor: so that it answers whether a weak object refers
to a young object. The old version only scanned weak fields, igoring refs to
young objs from strong fields.
Move check for valid classes from findClassOfMethod: forReceiver: into
findClassContainingMethod:startingAt:, hence making
findClassOfMethod:forReceiver: et al more robust.
