As it happens I was playing around with adding support for that today at least to get us started. I was going to put something up for review based on this patch, assuming this gets merged first. However in the TTI method we're currently making use of some `RISCVSubtarget` properties to help refine the vscale range, so we'll need to think about how we'll deal with those.
