Would be good to have most tests target independent if possible, with forced factors, unless they test the cost model.

Also, could you add tests for re-vectorizing from narrow fixed VF to wider fixed VF / narrow scalable VF to wider scalable VF, assuming `-force-vector-width=` works as expected? At least it should be rejected if it cannot be done
