I wonder if it's necessary to run `utils/update_test_checks.py` on this test, since all you're really testing is that we vectorised with a particular VF. For example, you could reduce the number of CHECK lines in each function to just the bare minimum:

```
; CHECK-LABEL: define void @NeoverseV2(
: CHECK:    store <4 x float>
```
