Reviewed by Simon Fraser.

Source/WebCore:

Make RenderLayerBacking::layerTreeAsText() (including internals.layerTreeAsText()) always
report that the main frame's RenderView layer is opaque when running iOS DumpRenderTree to
avoid test failures and the need to maintain for iOS WebKit1 an almost identical copy of the
platform-independent compositing test results.

The main frame's RenderView layer is always transparent in iOS WebKit1 since it does
not make use of a tiled cache layer and defers to UIKit to handle the final compositing
of the web view, including applying the page scale factor.

* platform/RuntimeApplicationChecksIOS.mm:
(WebCore::applicationIsDumpRenderTree): The app bundle identifier of DumpRenderTree has
the form org.webkit.DumpRenderTreeX where X is some non-negative integer.
* platform/graphics/GraphicsLayer.cpp:
(WebCore::GraphicsLayer::dumpProperties): Modified to report that a layer is opaque when
GraphicsLayerClient::needsIOSDumpRenderTreeMainFrameRenderViewLayerIsAlwaysOpaqueHack() returns true.
* platform/graphics/GraphicsLayerClient.h:
(WebCore::GraphicsLayerClient::needsIOSDumpRenderTreeMainFrameRenderViewLayerIsAlwaysOpaqueHack): Added
default implementation (returns false).
* rendering/RenderLayerBacking.cpp:
(WebCore::RenderLayerBacking::needsIOSDumpRenderTreeMainFrameRenderViewLayerIsAlwaysOpaqueHack): Added;
returns true when running in DumpRenderTree and the passed GraphicsLayer corresponds to the main frame's
RenderView layer.
* rendering/RenderLayerBacking.h:

LayoutTests:

Update test expectations and remove an unnecessary test result.

* platform/ios-simulator/TestExpectations:
* platform/ios-simulator/compositing/backing/backface-visibility-flip-expected.txt: Removed.
