Merge r181513 - Remove a redundant repaint when a layer becomes composited
https://bugs.webkit.org/show_bug.cgi?id=142711
Reviewed by Anders Carlsson.
RenderLayerCompositor::computeCompositingRequirements() doesn't need to call
repaintOnCompositingChange() when a layer is going to become composited,
because updateBacking() does exactly the same thing. I used an assertion
and ran the tests to ensure this wasn't a behavior change.
