Revert 168908 "Col width is not honored when dynamically updated..."

> Col width is not honored when dynamically updated and it would not make table narrower
> 
> Increasing the table width by increasing the colgroup width was working
> but decreasing the table width by decreasing the colgroup width is not working.
> 
> When colgroup width is defined table cell should adjust according to that.
> On decreasing colgroup width the cells maxPreferredLogicalWidth was
> still set to the earlier value. Setting the setPreferredLogicalWidthsDirty
> to true so that cells pref width is calculated again.
> 
> I already landed this patch on webkit. Just modified the layout test file and fixed build errors.
