99c91e021a Do not mark ALL terminators live if any instruciton in the block is live. We only 
want to mark it live if it is an unconditional branch.  This fixes bug:
ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful.

34e353e560 Fix bug: ADCE/2003-06-11-InvalidCFG.ll 
This was because we were deleting large chunks of functions without an exit block, because the post-dominance
information was not useful.  This broke crafty and twolf.

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.

446698b63d * Fix bug: test/Regression/Transforms/ADCE/2002-07-17-AssertionFailure.ll 
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.

  the analyses themselves.

f57b845547 * Rename MethodPass class to FunctionPass 
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well
