I don't think AVX supports true 256-bit integer. On the other hand, I was
also puzzled by compute_record_mode, which excludes UNION_TYPE and
QUAL_UNION_TYPE. Will including them break union

Please note that there is currently no way to generate OImode directly:
$ more oi.c
typedef int OItype __attribute__ ((mode (OI)));
OItype test (OItype a)
{
return a;
}

I'm working on vzeroupper insertion and my implementation inserts vzeroupper
before the call because VALID_AVX256_REG_MODE returns false.
