BUG=7973 Note: this is a breaking change and would be advertised as such. Anyone using js-interop would need to explicitly include: <script type="text/javascript" "pkg/browser/lib/interop.js"></script> along with dart.js in their HTML. Those who don't need js-interop can save on this code. Alexandre: I'm imagining interop.js would be the landing spot for dart:js bootstrap code as well.
