Tested on x86_64-linux (nehalem, cascadelake) x86_64-darwin (core2,
westmere, ivybridge, haswell, skylake, cascadelake). 42 progressions
on cascadelake, no regressions elsewhere.
OK for trunk?
thanks

These tests assume that 512b vectors will be selected and do scans
accordingly. However, for cascadelake tuning the preference will be
for 256b.
It would be possible to solve this by selecting generic tuning - but,
in this case, it is sufficient to prefer 512b vectors.
