0ae380a8ac Teach SplitCriticalEdge to update LoopInfo if it is alive. This fixes 
a problem in LoopStrengthReduction, where it would split critical edges
then confused itself with outdated loop information.

b01bfd49c3 Change break critical edges to not remove, then insert, PHI node entries. 
Instead, just update the BB in-place.  This is both faster, and it prevents
split-critical-edges from shuffling the PHI argument list unneccesarily.

a92f696b74 Updates to work with recent Statistic's changes: 
* 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.
    * Updated ProgrammersManual with new semantics.
