JDK-8146735 - Move sun.misc.PerformanceLogger to sun.awt.util
Description
We need to update com.sun.javafx.tk.quantum.PerformanceTrackerHelper in JavaFX to account for the move of sun.misc.PerformanceLogger to sun.awt.util in JDK-8146735.

We access this class via reflection, so it will be easy to look for it either in its new location or its old location (so we can still run tests with JDK 8u60).

@Mandy: I haven't looked at the class to know whether it would be easier to copy it. Given that this is now in java.desktop, though, it might be a good idea to look into it. Otherwise it will be yet another implementation dependency from javafx.graphics on java.desktop.

I note that explicitly passing null for the ClassLoader is fragile. Better would be to use PerformanceTrackerHelper.class.getClassLoader() which is what we do in other places.

Would it be easier to make a copy of PerformanceLogger (unless it is intended to record events from both JavaFX and java.desktop)?

The following is the only reference to this class in JavaFX: com.sun.javafx.tk.quantum.PerformanceTrackerHelper: final Class perfLoggerClass = Class.forName("sun.misc.PerformanceLogger", true, null); This will be a straight-forward fix. Until then, the performance logger will be ignored (the code gracefully handles the case where the class cannot be found).
