Make SCEVUnknown a CallbackVH, so that it can be notified directly
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.

Speculatively revert r109705 since it seems to be causing some build bot
angst.

Factor out some of the code for updating old SCEVUnknown values, and
extend it to handle the case where multiple RAUWs affect a single
SCEVUnknown.
Add a ScalarEvolution unittest to test for this situation.
