Crash from multicol spans with layers
https://bugs.webkit.org/show_bug.cgi?id=68030

Patch by Ken Buchanan <kenrb@chromium.org> on 2011-12-07
Reviewed by David Hyatt.

Source/WebCore:

The layer tree diverges from the render tree when a span is being split
between columns. This patch causes the layer tree to be updated when necessary.

* rendering/RenderBlock.cpp:
(WebCore::RenderBlock::splitFlow)
(WebCore::RenderBlock::splitBlocks)

LayoutTests:

New test for fix to crash on bug 68030.

* fast/multicol/span/removal-of-multicol-span-crash-expected.txt: Added
