Currently, JFR is enabled by default on all platforms that support it, and it cannot be disabled. We have been using `-XX:+FlightRecorder` to indicate if the JVM should start with recording enabled. This is not consistent with the RI. With this change `-XX:[+|-]FlightRecorder` toggles whether JFR is enabled. By default JFR will remain enabled, but we now have the ability to disable it. `-XX:StartFlightRecording` will be used to indicate that a recording should be begin at startup.
