Make QVM-INTRINSICS work again. #289

Change MAKE-EA to EA.
Test for AVX2 in a different way, as we're not allowed to test sbcl internal features anymore.

We need to figure out how to make sure this won't break downstream users. I don't think all current virtualized cloud users of QVM have AVX2 but do benefit considerably from the intrinsics.

OK, I think we can just frob (sb-alien:extern-alien "avx2_supported" int) then to do the check. Maybe just checking it at read time is enough.
