Test: fast/dom/Window/property-access-on-cached-window-after-frame-removed.html
Properties of a contentWindow could be accessed even if the frame who owns the window is
detached. Therefore, check whether the document loader is still alive before using it.

(WebCore::PerformanceTiming::monotonicTimeToIntegerMilliseconds):
Tools:
* WebKitTestRunner/InjectedBundle/mac/TestRunnerMac.mm:
(WTR::TestRunner::inspectorTestStubURL):
Since WebInspectorUI.framework is not available for iOS, the framework
and corresponding functions are disabled in iOS.
