Alan, please, correct me if I'm wrong: does it mean that we can just
stick to marking new instructions and facilities with a custom per-CPU
flag? For now I introduced the -mlibresoc CPU which enabled the
PPC_OPCODE_SVP64 flag, and marked some new instructions appropriately
with this flag. Would that be OK if we follow this approach?
