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

[Charles Saternos via Phabricator via llvm-commits]

I don't think I can use a topological sort in this case since the FunctionSummary callgraph isn't necessarily a DAG, so if there's a cycle it would make the sort useless.

Instead, I tried using the main function as the entry node and that worked. Any suggestions on a clean way of implementing this rather than hard coding a lookup for "main" in the Index?
