Created an attachment (id=107534)

Changes for review comments

1. I've moved invalidating cache into styleDidChange() method and guarded it with parent()/table()/needsLayout() check before comparing border values. Only table's needsLayout() is used because we invalidate cache only in RenderTable::layout().

2. Fixes for small things.
