FrameView::updateLayerFlushThrottlingInAllFrames() should call FrameView::frameLoadProgressingStatusChanged(Frame*)

FrameView::frameLoadProgressingStatusChanged() calls
    updateLayerFlushThrottlingInAllFrames();
    adjustTiledBackingCoverage();

FrameView::updateLayerFlushThrottlingInAllFrames()
{
    bool isMainLoadProgressing = frame().page()->progress().isMainLoadProgressing();
    if (frame().page()->chrome().client().adjustLayerFlushThrottling(isMainLoadProgressing))
        return; // client handled throttling
    ...
}

Maybe have:

enum ThottleState {
    MainLoadProgressing = 1 << 0,
    UserIsInteracting = 1 << 1
    ...
};

typedef unsigned ThottleStateFlags;

ChromeClient::adjustLayerFlushThrottling(ThottleStateFlags);
