Improve histogram and timing logger dumping.
We now dump the sum (total time) of each histogram as well as
previous stats. This is useful for the GC since the same split can
occur multiple times per GC iteration. Also did a few memory
optimizations by changing the map in the cumulative loggers
to be a set.
