ASSERTION FAILED: m_repaintRect == renderer()->clippedOverflowRectForRepaint(renderer()->containerForRepaint()) after r135816
https://bugs.webkit.org/show_bug.cgi?id=103432

Reviewed by Allan Sandfeld Jensen.

Remove optimization added in r99752 that attempted to avoid clip rect
updates for table cells. As the assertions show, this optimization
is not always correct, so remove it. Bug 108272 tracks adding it back in.

* rendering/RenderLayer.cpp:
(WebCore::RenderLayer::RenderLayer):
(WebCore::RenderLayer::updateLayerPositionsAfterScroll): Remove m_canSkipRepaintRectsUpdateOnScroll
check when updating clip rects.
* rendering/RenderLayer.h: Remove the m_canSkipRepaintRectsUpdateOnScroll bit.
