For the `VectorIntrinsics.checkFromIndexSize`, I'm afraid it's not suitable to be used here because the `outOfBounds` exception will be thrown if the offset is not inside of the valid array boundary. And  for the masked operations, this is not needed since we only need to check the masked lanes. Please correct me if I didn't understand correctly. Thanks!

Good idea! I will try. Thanks!
