After bad commit:
commit 6107557f8fa34e0b7191813792be43eaa03aed19
Author: Kenneth Graunke <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>>
Date: Wed Oct 22 08:58:59 2014 -0700
i965: Re-enable Z16 on Gen8+.
Improves performance in GLBenchmark 2.7 TRex by 3.88889% +/- 0.336383%
(n=80) at 1280x720 on Broadwell GT3. Together with the previous patch,
it improves performance by 5.42738% +/- 0.541971% (n=10) at 1920x1080.
Note that without the PMA stall fix, this would instead decrease
performance by 22%.
v2: Update comment (noticed by Kristian Høgsberg).
