The rewrites look good, though I wonder if it'd make more sense to include these in the `-arm-sme-outer-product-fusion` pass instead? They'd work just as well there, and that would also ensure no pass between `-arm-sme-vector-legalization` and `-arm-sme-outer-product-fusion` moves them again (due to some random canonicalization).
