Dan Gohman 68ac0492a4 Make SCEVUnknown a CallbackVH, so that it can be notified directly ...

of Value deletions and RAUWs, instead of relying on ScalarEvolution's

insufficient in general.

This means SCEVUnknown needs a non-trivial destructor, so introduce
a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.
