Uh but the kernel RVV code requires an assembler that supports the `.option 
arch` directive and the V extension anyway.

Is there a need to wrap vector load/store and ALU instructions from the Vector 
spec? This trick should only be necessary for the Zvk*-specific stuff, AFAICT.

(Also FWIW, this can be done directly with .macro inside a header file, without 
involving Perl.)
