[PATCH] D72214: [GlobalOpt] Get DT only if it is available.

[Ehud Katz via Phabricator via llvm-commits]

ekatz added a comment.

The old PassManager has the function `getAnalysisIfAvailable` that should be used in case you only need to update an analysis (equivalent to `getCachedResult` of the new PassManager). You should probably switch to use this function, instead of the `SmallPtrSet<> DTRequested`.
