Neither of those vec_perms are valid targets for this optimization.
It looks like sel.series_p is not doing what I expected. It's matching even
elements and ignoring the odd ones.

Jakub, you are too fast! Anyway, nice test-case. So far I was able to come to
something semi-reduced:

I think series_p clearly documents that:
