Deserialize UMA flag on histograms moving from renderer to browsers
Deserialize UMA flag on histograms moving from renderer to browsers

During a recent migration, we forgot to properly resurrect the
flags in a histogram as they are carried from the renderer processes
into the browser process. Since the flag is the critical marker that
identifies which histograms to upload via UMA, this caused renderer
histograms to not get reported.
