Pretend AMD XOP was never a thing.

It's not clear that any AMD XOP code paths are being properly tested.
AMD dropped XOP starting in Zen.

Here's the one place I found (without looking too hard) where it seems
there is a XOP code path in BoringSSL, in sha512-x86_64.pl. Most of the
other XOP code was removed.

```
$code.=<<___ if ($avx && $SZ==8);
	test	\$`1<<11`,%r10d		# check for XOP
	jnz	.Lxop_shortcut
```
