Chris Lattner 03507809a0 The new CFrontend generates LOTs of basic blocks that just fall through and do
other funky stuff.  Clean it up early.

Chris Lattner 387d76a983 * 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.

Chris Lattner c70222dc15 * No longer need to run die after instcombine
* Run new correlated expressions pass
* Simplify the CFG (removing dead blocks, merging blocks, eliminating branches
  on constant booleans, etc) after correlated exprs pass.

Chris Lattner 3f5b42697c - Reformat comments
- 'gccas' puts verifier in logical place in pass procession to avoid
    recomputing dominator information unneccesarily.

Chris Lattner c065ad850c Make sure that there is no case where a signal can occur leaving a partially
written output file.  This is important because crashing testcases often write
part of a file out, and the testing harness decides the file is up-to-date next
time the test is run.

charactaristics.
