--- Comment #3 from Kenneth Graunke <kenneth at whitecape.org> ---
Broadwell cannot have a performance regression due to this commit, as that
commit only changes Gen4-7 code generation.  Gen8+ was completely unaffected.

According to QA's performance tracking page, Synmark OglBatch0 performance
actually increased by 8% between 8/06 and 8/13 on Broadwell.  Which is very
different than a 10-90% performance regression as reported.
