Summary: Release notes: upgrades Prepack to use Babel 7.0.0-beta.53 This is a big PR that updates all of Prepack to Babel 7. Babylon is now `babel/parser` and pretty much all of the the previous Babel packages are now located in scoped packages. I had to make a bunch of changes around Jest/Flow/Webpack to get this all working. The build times of building Prepack itself seem considerably faster (easily twice as fast locally). I followed most of the Babel 6 -> 7 upgrade guide from the Babel site in terms of changing nodes and type definitions to match the new ones.
