We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.
Mechanical change doing:
$ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)

Since we *might* have user emulation with softmmu,
use the clearer 'CONFIG_SYSTEM_ONLY' key to check
for system emulation.

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;
}

create a separate tcg/sysemu/fpu_helper.c for the sysemu-only parts.
For user mode, some small #ifdefs remain in tcg/fpu_helper.c
which do not seem worth splitting into their own user-mode module.

smm is only really useful for sysemu, split in two modules
around the CONFIG_USER_ONLY, in order to remove the ifdef
and use the build system instead.
add cpu_abort() when detecting attempts to enter SMM mode via
SMI interrupt in user-mode, and assert that the cpu is not
in SMM mode while translating RSM instructions.
