 * A stopwatch measuring the duration of a CPOW call.
 * As the process is consuming neither user time nor system time
 * during a CPOW call, we measure such durations using wallclock time.
 * This stopwatch is active iff JSRuntime::stopwatch.isActive is set.
 * Upon destruction, update JSRuntime::stopwatch.data.totalCPOWTime.
class MOZ_RAII CPOWTimer final {
    explicit inline CPOWTimer(JSContext* cx MOZ_GUARD_OBJECT_NOTIFIER_PARAM);


     * The context in which this timer was created, or `nullptr` if
     * CPOW monitoring was off when the timer was created.
    JSContext* cx_;

     * The instant at which the stopwatch was started. Undefined
     * if CPOW monitoring was off when the timer was created.
