JDK-8273486 - Zero: Handle DiagnoseSyncOnValueBasedClasses VM option
Description
While fixing JDK-8273486, I noticed there is one place where we do not call VM slowpath when UseHeavyMonitors are requested. That place is ZeroInterpreter::native_entry. We should probably implement UseHeavyMonitors check on those paths.
