[Mesa-dev] [PATCH] i965/gen9: Use raw PS invocation count for queries

[Ben Widawsky]

Previously the number needed to be divided by 4 to get the proper results. Now
the hardware does the right thing. Through experimentation it seems Braswell
(CHV) does also need this.

Fixes piglit test:
arb_pipeline_statistics_query-frag
