Thanks for this! Can we use the labels as requested in the review comments?

src/hotspot/share/gc/shenandoah/shenandoahConcurrentMark.cpp line 228:

Could we pass `"Finish Mark"` for the label here.

src/hotspot/share/gc/shenandoah/shenandoahSTWMark.cpp line 136:

Could we pass `"Mark"` for the label here?
