Handle direct call ReadyToRun helpers

Add missing check in the JIT to generate correct code for direct call ReadyToRun helpers. I have run into this bug while experimenting with ReadyToRun optimizations. It is not observable bug today because of crossgen happens to always emit ReadyToRun helpers as indirect calls.
