Dan Gohman ab37f50838 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110086 91177308-0d34-0410-b5e6-96231b3b80d8		2010-08-02 23:49:30 +00:00
