+2019-10-08  Ryosuke Niwa  <rniwa@webkit.org>
+
+        Make WebInspector's remote debug EventLoop code into RunLoop
+        https://bugs.webkit.org/show_bug.cgi?id=202716
+
+        Reviewed by Joseph Pecoraro.
+
+        Updated the code to use RunLoop::cycle instead of now deleted EventLoop class.
+
+        The runloop mode used in Apple's port is moved to RemoteInspectionTarget::runLoopMode
+        with a special case for watchOS.
+
+        * JavaScriptCore.xcodeproj/project.pbxproj:
