Without this patch, jvm will crash on SVE with Vector API, so I want to get this into 'vector-unstable' for integration
into jdk. Do you think it make sense? Current vectorIntrinsics is a bit behind vector-unstable and jdk/jdk, e.g.
without Arm SVE support yet, so this patch cannot apply to vectorIntrinsics. We need to merge vector-unstable into
vectorIntrinsics first.
