*) I don't understand the move in shenandoahBarrierSet.cpp -- does it correct the method placement
to its location in 8233339?

*) Do we really need 8238574? Notice in the original changeset it checks the result of LRB_native:
  https://hg.openjdk.java.net/jdk/jdk/rev/8d8916159b62
 ...is it even possible with non-native LRB in 11u?

Otherwise looks fine.
