commit 86b6c8ce661bf08b2650bf35bc96d79600095d80
Author: wfh <wfh@chromium.org>
Date: Fri Jul 15 20:48:35 2016

Add renderer launch count to stability metrics.

This will make it possible to have a more meaningful measure of true extension
renderer stability as currently there is no denominator that can be used for
normalization of extension stability.

Desktop/Android only.
