[Libre-soc-dev] pysvp64asm: opcode setvli not supported

[Luke Kenneth Casson Leighton]

example showing why macro processing is needed:

 # sv.fmuls/mr sum, fv0.v, fv1.v

although the FRT can be identified as scalar, the prefix abd suffix
are calculated from the *register number*.

"sum" is not a number, and to understand it the python svp64
converter, which is supposed to be very very simple and not duplicate
functionality of binutils gas, would have to understand the exact
binutils macro substitution.

i will think about it because for bare minimum functionality it might
be ok to implement.
