I think the premiss that you want the loop explicitly unrolled is wrong, as

What we can do, trivially, is increase LMUL.
I don't have access to the source, but gcc should produce the exepcted codegen
with -mrvv-max-lmul=dynamic. I don't know what that isn't the default and
instead gcc doesn't produce LMUL>1 by default, but that is another problem.
