I've created [JDK-8366531](https://bugs.openjdk.org/browse/JDK-8366531) for `VectorReinterpret` and [JDK-8366532](https://bugs.openjdk.org/browse/JDK-8366532) for `StoreVector`. I've assigned `VectorReinterpret` one to myself and I left the other one unassigned for someone else to maybe pick it in the future?
