If the checks that are present (e.g. in RenderBlockLineLayout.cpp, RenderImage.cpp) are indeed worth doing, they are potentially also worth doing in RenderBlock.cpp and RenderWidget.cpp, and RenderText.cpp, and RenderMenuList.cpp, and .... Or we could instead just add a single: if (UNLIKELY(AXObjectCache::accessibilityEnabled())) to Document::existingAXObjectCache().
