target/i386: Remove user-only i/o stubs
...
With the previous patch for check_io, we now have enough for
the compiler to dead-code eliminate all of the i/o helpers.

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;
}
