Thanks to facebook/regenerator#167 Regenerator's runtime can be now required as a module (though not in an easily self-containable way). This transformer, together with `coreAliasing` and `externalRuntime`, allows users to ditch a runtime dependency on `6to5`/`6to5-core` to depend directly on `core-js` and `regenerator`.
