There are some xtheadvector instructions that differ from RVV1.0
apart from simply adding "th." prefix. For example, RVV1.0
load/store instructions will have SEW while xtheadvector not;
RVV1.0 will have "o" for indexed-ordered store instructions while
xtheadvecotr not; xtheadvector and RVV1.0 have
ok.
