* Remove the -stopraise option, which is no longer needed now that we have

the -debug-pass=Arguments option
* Run instcombining BEFORE mem2reg so that getelementptr X, long 0's are
  cleaned up.  This is also important because scalar replacement of aggr.
  will want instcombine to run before it goes as well.
