      Description

        This is a spin-off the JDK-8331911, but for Shenandoah specifically. JDK-8331911 would likely be more intrusive that initially anticipated, and we want something that fixes a customer case with Shenandoah quickly.

        We can transplant the hunks for `ShenandoahBarrierSetNMethod::nmethod_entry_barrier` from JDK-8331911 into a separate issue here.
