Sorry it took me so long to review this!

> The SVE support generates unsigned comparison predicates for comparisons of signed types. This looks very unintuitive to me, so I changed it to use signed comparisons. I think the SVE case may just be a bug?

Looks like I made a mistake here when I originally wrote this for SVE, thanks for pointing it out! It looks like someone has already fixed this in clang trunk since, thankfully.

Could you add an `Assisted-by:` tag to the PR description as per the [AI Tool Use Policy](https://llvm.org/docs/AIToolPolicy.html)? Thanks!
