[PATCH] D37957: [TableGen] Some simple optimizations to TableGen execution time

[Zachary Turner via Phabricator via llvm-commits]

Changed another `std::set` to a `DenseSet`, and changed a couple of sets to vectors.  This shaves off another couple of seconds, I'm now down from 45s (no patch) -> 26s (with patch), for a 1.73x combined speedup.
