This should be enough to allow statically compiling swift applications. As followups, I'm going to additionally start installing swift.swift to a common location, and start making REPL/script mode aware that these functions are available, so they don't bother to IRGen them. I'm leaving around some files in runtime/ which aren't necessary with this commit; I'll delete them in a separate commit. Swift SVN r1725
