cleaned up. This is also important because scalar replacement of aggr.
will want instcombine to run before it goes as well.

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
