Hi @craig.topper, good point! I've added a check that the target supports scalable vectors and that we know the minimum page size. Although the pass currently lives in lib/Target/AArch64 it is generic enough that it could be moved into a common directory and used by other targets.

It might make sense to move this patch into github soon for a full review, even though I prefer Phabricator. :)
