[CSS Regions] Implement visual overflow computation for inline elements

[Andrei Bucur]

Currently only RenderBoxes have visual overflow computed per region. This means inline elements are incorrectly handled.

There's a FIXME in RenderFlowThread::regionForCompositedLayer: "remove this when we'll have region ranges for inlines as well"

Why the FIXME comment? Just add the assert.

This patch doesn't provide ranges for inline elements (e.g. a div with display: inline-block), but the means to access the visual overflow in regions for more elements (RenderInlines in this case).

all tests should mention the number of the bug they test.
