    Make SCEVUnknown a CallbackVH, so that it can be notified directly · 7cac9577
    Dan Gohman authored
    of Value deletions and RAUWs, instead of relying on ScalarEvolution's
    Scalars map being notified, as that's complicated at best, and
    insufficient in general.
    
    This means SCEVUnknown needs a non-trivial destructor, so introduce
    a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.
