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).
