Reviewed by Alan Baradlay.

This patch is to fix repaint issue in WebKit, which is not present in Blink / Chromium and Gecko / Firefox.

Merge - https://src.chromium.org/viewvc/blink?view=rev&revision=196609

By not including visual overflow effects results in incorrect paint invalidation (as exhibited by the attached test), and also incorrect painting.

* Source/WebCore/rendering/RenderTable.cpp:
(RenderTable::simplifiedNormalFlowLayout): Account for 'addVisualEffectOverflow'
(RenderTable::layout): Ditto
* LayoutTests/fast/repaint/table-section-visual-overflow.html: Add Test Case
* LayoutTests/fast/repaint/table-section-visual-overflow-expected.txt: Add Test Case Expectation
