I think the default range should still be the same - somewhere between 1 and 
16. SME doesn't increase that even if they VL and SVL are different.

(Currently if we have +sve+sme we will set the vscale_range to (1,16) already, 
so hopefully that part is already OK. In either case this adds the simple case, 
it doesn't alter the more complicated part :) )
