      Description

        Currently, Shenandoah STW ops use ShenandoahHeap::gc_timer() to register the GC times. But that GCTimer is actually ConcurrentGCTimer! Concurrent ops should be calling to that, and STW ops should be doing their own STWGCTimer. This might interact with the existing Shenandoah+JFR support
