cc377df7f5 * 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.

0a4aa5a026 gcc3.1.1 seems much more selective about what it loads from archives, and
does not link in many passes that are loaded by gcc2.95.3.  So use object
files instead of archives in many more cases.

4dd7d3e34d * 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.

c5394837fe - Reformat comments
- 'gccas' puts verifier in logical place in pass procession to avoid
    recomputing dominator information unneccesarily.

76d12299b5 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.
