      JDK-8228369 broke C1's getAndSetObject() intrinsic with Shenandoah:

      # Internal Error (/home/shade/trunks/jdk-jdk/src/hotspot/share/c1/c1_LIRGenerator.hpp:224), pid=20194, tid=20205
      # assert(!opr->is_register() || opr->is_virtual()) failed: should never set result to a physical register

      V [libjvm.so+0x782a67] LIRGenerator::do_UnsafeGetAndSetObject(UnsafeGetAndSetObject*)+0xe7
