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.

which was caused by us not running the "drop references of dead
instructions" code when there were no basic blocks that were dead.
We still don't want to do some of the stuff we do if there are dead
basic blocks, but we DO want to drop references of dead instructions,
so we factor the common code out to a new method.
