Sure.

This is the src/hotspot subset of the merge:
  https://cr.openjdk.java.net/~shade/shenandoah/merges/jdk11-11.0.8%2b1/webrev.01/

...for this, I resolved the conflict in src/hotspot/share/opto/loopnode.cpp by accepting the
upstream side, and then applied a hunk in src/hotspot/share/gc/shenandoah/c2/shenandoahSupport.cpp
cleanly. There were no other conflicts.

Without doing the above, gc/shenandoah/compiler/CallMultipleCatchProjs.java fails.
