Subject: [PATCH] Create the somewhat confusingly named MaxValueIntStat --
 there's already a MaxIntStat here, which tracks the maximum value that the
 stat has been incremented by; MaxValueIntStat tracks the maximum value that
 the stat has ever attained.

Maybe these two classes should be merged into one? I'm worried that might break other code that already relies on MaxIntStat. Brighter minds: please advise.
