* 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.

files instead of archives in many more cases.

  on constant booleans, etc) after correlated exprs pass.
