This PR lets the backend compile jumps to side exits using
Target::SideExitPtrinstead ofTarget::CodePtrto avoid filling unnecessarynopinstructions after such jumps.The backend assumes any
Target::CodePtrcould be invalidated due to patch points or chain guards. However, we never invalidate side exits. So, in YJIT, we introducedTarget::SideExitPtrto distinguish side exits from other jumps.
