[PATCH] D62970: [clang-doc] De-duplicate comments

Actually if we can make Description a hash set that would be best. I think using std::set would require an awkward < operator to be defined. There should be standard ways of getting hashes out of all the string and vector types and you can use hash_combine to combine all of these into a single hash.
