Claudio Fontana b39030942d i386: split svm_helper into sysemu and stub-only user
For now we just copy over the previous user stubs, but really,

everything that requires s->cpl == 0 should be impossible
to trigger from user-mode emulation.

Later on we should add a check that asserts this easily f.e.:

static bool check_cpl0(DisasContext *s)
{
     int cpl = s->cpl;
 #ifdef CONFIG_USER_ONLY
     assert(cpl == 3);
 #endif
     if (cpl != 0) {
         gen_exception(s, EXCP0D_GPF, s->pc_start - s->cs_base);
         return false;
     }
     return true;
}
