RenderNamedFlowThread layers should not be composited and their collected children layers should be inspected by means of their associated regions.

r=me, but we should also add a bug to fix the initial assert when proper compositing is implemented.

> LayoutTests/fast/regions/assert-flow-thread-compositing.html:5
> +            .transformed { width: 50px; height: 50px; background-color: salmon; -webkit-transform: translateZ(0px); border: 1px solid black; }

nit: just use green instead of salmon :)

> Source/WebCore/rendering/RenderLayerCompositor.cpp:926
> +        layer->setHasCompositingDescendant(false);

nit: I think you don't need this, it's false by default. We are going to fix it for 84900 anyway.
