v642+ of libsyntax and friends is now needed to compile on nightly. We've updated rustfmt to use v642 (https://github.com/rust-lang/rustfmt/pull/4043) and this does the same for Racer so that Rls can subsequently be updated as well.
This is my first contribution to Racer so please let me know if I've missed anything/need to do anything else!
