I'm tempted to suggest that you leave it in but #ifdef it PLATFORM(IOS), since I'm not sure that we'll want to do automatic composited scrolling on iOS yet.

- Removed tests specific to -webkit-overflow-scroll.
- Converted other composited scrolling tests to use
  setAcceleratedCompositingForOverflowScrollEnabled() instead. These should
  pass on all platforms that support accelerated compositing.
- Enabled composited overflow scrolling in ScrollingCoordinatorChromiumTest.

[Sami Kyöstilä]

Ah, I missed your comment Simon. I'll do another round to leave the flag in but disable it just for Chromium. I think the tests can also be made to work in both modes.
