1.4%-83.3% regression in webrtc_perf_tests at 18313:18313

Project Member Reported by terelius@chromium.org, Jun 15 2017 
Changes caused by setting is_clang=true by default on Windows. This was done as an experiment over the weekend. Mostly improvements.

Stefan, do you see why a compiler change (that seems to optimize the code better) would cause a decrease in bitrate and encoded frame rate, and more dropped frames?
