  Message : Add histograms helper macros. These macros mimic Chromium's histogram_macros.h, so we can use similar values for our histograms. BUG=angleproject:944 BUG=436191 Change-Id: If77abaf71964d26a6269183e51b68b76bb562085 Reviewed-on: https://chromium-review.googlesource.com/266523 Tested-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Zhenyao Mo <zmo@chromium.org>
