This macro is attempting to force a value to a particular class of
register, we don't need or want the mov instruction at all.  Isn't
something like this sufficient:

#define force_simd(V1)   asm volatile (""       \
          : "+w"(V1)                            \
          :                                     \
          : /* No clobbers */)

?
