Isn't that pattern a vpblendb or some such ?
I think Kieran already responded to this on IRC but I will too.
Unfortunately not. This blend is at the bit level. This is v210 so the
packing has the middle sample overlapping with the bottom sample in the
second byte.
I also want to amend my performance numbers on Broadwell. I can confirm
Kieran's disagreement and can reproduce the 10% speed up on it:
1676±14.6 vs 1426±20.9
I will re-check Zen and amend the commit message as necessary.
