63a32de776 - Generic graph printing infrastructure changes: 
* Only print outgoing edges from a cell if the destination isn't null.
       This is important for DSGraphs, which have sources with no edges.
     * Allow Node attributes to override shape of the node

b0d0f5b473 The wall clock timer (implementing using the RTC or cycle counter on x86) is 
so much more accurate than the per process timers that we get better results
(less noise) by sorting according to wall time than process time.

96ef1b90c8 - Rework Statistics: 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
