CodeGen: Eliminate a use of getDarwinMajorNumber().

- There is a minor semantic change here (evidenced by the test change) for
   Darwin triples that have no version component. I debated changing the default
   behavior of isOSVersionLT, but decided it made more sense for triples to be
   explicit.
