We can not return `StringSet` from the start because it is a hashtable, and we need ordering for future use. The only option I see is to use `std::set` (which is not a good data structure IMO). [LLVM guide suggests](https://llvm.org/docs/ProgrammersManual.html#a-sorted-vector) sorted vector is a good thing, so I removed dependency on `StringSet` and used `llvm::binary_seach` instead.
