I had to omit `_interfaces` in `TypeInstPtr::with_speculative` because [JDK-8297933](https://bugs.openjdk.org/browse/JDK-8297933) is not in 17u. The context differs to some degree, but all modifications are integrated (each line). The test update applies cleanly. Please review!

Thanks for the review!
