See for instance: https://ci.chromium.org/buildbot/chromium.linux/Linux%20Tests%20(dbg)(1)/69628 I think it was green before the weekend, but the history doesn't seem to go back that "far". Reproducible locally.

This revert also seems to fix a bunch of WebRtcGetUserMediaBrowserTest regressions, like the ones seen here: https://ci.chromium.org/buildbot/chromium.linux/Linux%20Tests%20%28dbg%29%281%29/69631
This has been fixed in SwiftShader and the following roll has already landed.
