Message:

REGRESSION: Extremely flashy scrolling while a page is still loading (because of flush throttling)
​https://bugs.webkit.org/show_bug.cgi?id=135603
<rdar://problem/17876385>

This hit ASSERT(frame().isMainFrame()) in FrameView::updateLayerFlushThrottling
running scrollbars/scrollbar-iframe-click-does-not-blur-content.html and a few other tests.

• page/FrameView.cpp:

(WebCore::FrameView::setWasScrolledByUser): Only invoke updateLayerFlushThrottling for the main frame.
