Right, there is no adjustment anymore on any platform.  I think this function and verify_deopt_original_pc only ever existed to support code that is now getting removed.  So I could change the name to verify_unextended_sp() and make it const, but it might make more sense to remove both this function and verify_deopt_original_pc now.  What do you think?
