I think this is a good idea, though it's a little tricky becuase the typespecs
`'c'`, `'s'` ,`'i'` and`'l'` are often seen following a typespec modifier in
arm_sve.td to change the element size (e.g, for predicates/SVCounts as you
described before), and as typespecs in their own right (referring to the signed
integer of their size, which is where the `Kind(SInt)` default comes from). One
way to go about this is to make `'c'`, `'s'` ,`'i'` and`'l'` default to `SInt`
if there is currently no type set, and leave the type unmodified if otherwise.
Any thoughts?
