Subject: iris: Make shader_perf_log print to stderr if INTEL_DEBUG=perf is set
X-Git-Tag: upstream/19.3.0~7312
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=024a57d23c87b6c55f71e092f60c83a58fcce2e5;p=platform%2Fupstream%2Fmesa.git

iris: Make shader_perf_log print to stderr if INTEL_DEBUG=perf is set

This matches i965's behavior, and makes sure that shader compiler
messages are visible when setting INTEL_DEBUG=perf.
