Dan Gohman 7cac95778f 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. llvm-svn: 110086		2010-08-02 23:49:30 +00:00
