Ben Newman b3acf9100e Make babel-runtime use regenerator-runtime from npm. (#3494)
The source repository for regenerator-runtime can now be found at
https://github.com/facebook/regenerator/tree/master/packages/regenerator-runtime

This also removes the babel-regenerator-runtime package, now that the only
difference between it and regenerator-runtime has been resolved:
