Summary Potential crash with RenderLayer clipRects

Bug 20066 changed RenderLayer::calculateClipRects() to not call parent()->calculateClipRects() in some situations. That means that the parent's clipRects are no longer guaranteed to be set up, so the code lower in the method needs to protect against this.
