Related to @craig.topper comment at https://reviews.llvm.org/D93175#2452890 do we want the ,ta,mu markers appear here?

I'd say so but maybe we have to to update earlier tests in the way?

I agree. We should have ",ta,mu" in vsetvli instructions. I think I missed the modification in some test cases. I will update them. Thanks for pointing it out.
