[PATCH] D36311: [ThinLTO] Add GraphTraits for FunctionSummaries

I tried implementing a search to find the root nodes in the Index callgraph. But there can be multiple root nodes in the callgraph and we can only return one node from GraphTraits<ModuleSummaryIndex *>::getEntry. Since I didn't know how to pick the correct root, I didn't go with that solution. Is there any information I can find in the Index that indicates the entry point?
