Teresa Johnson 446d067392 [ThinLTO] Make distributed indexes test more robust
Modify test so that it passes in the reverse-iteration bot.
We use DenseMap instead of std::map for the summaries to emit into
distributed index files. The iteration order is not defined, but
it is deterministic, which is good enough.
