  Message : Reland "Replace gl::trace logging with Chromium style logging" Removing one usage of FormatString() and its static buffer. And preparation for Platform logging. Fix incorrect enabling of ERR() calls in UNIMPLEMENTED() and UNREACHABLE(), resulting in increased code size and <iostream> adding 5 static initializers to chrome because of cerr referenced in statically linked translator. BUG=angleproject:1660 Change-Id: I7caa18036118d532e0544f75278602559172ae04 Reviewed-on: https://chromium-review.googlesource.com/431457 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
