b3414f7cb6 The levelraise pass is a broken old piece of crufty code that should be 
left on the side of the road without a second thought.

It is preventing forward progress, so for now, we will disable it by default.

bugs and needs to be reworked anyway.

d01dffe97f * 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.

  on constant booleans, etc) after correlated exprs pass.

    recomputing dominator information unneccesarily.
