CTTE: RenderNamedFlowThread always has a WebKitNamedFlow.
<https://webkit.org/b/128623>
Codify the fact that RenderNamedFlowThread always has a corresponding
WebKitNamedFlow by storing it in a Ref, and adding an accessor that
returns a reference to get rid of all the ->'s.
Also removed some unnecessary assertions exposed by this.
