Shader-db results: The one shader hurt for instructions is a compute shader that had both spills and fills hurt. v2: Fix typo in comment noticed by Caio. v3: Fix inverted condition in brw_nir.c. Noticed by Lionel. Skylake, Broadwell, and Haswell had similar results.

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
