It might be worth defining a pseudo-instruction macro in asm.S that would 
statically compute the minimal LMUL from just the AVL and SEW. Then we don't 
to repeat these if blocks times and again, we can just do:

vsetvlstatic \len + 1, e8

or something like that

FWIW, it should be possible to include func and endfunc in the macro too.
