<pre>--Mesa Version--
mesa-19.0.0-rc1 or mesa-19.0.0rc2
--Hardware--
Intel Skylake Processor
--Description--
There seems to be about a -50% performance regression for Sascha Willems demo's
"Compute Shader" and "Compute Particles".
Also, a replay of a trace of dota2 also is experiencing a regression of about
-50% in performance.
These regressions are not seen in the Mesa 18.3 branch.
