Summary: Lately, I have submitted a number of patches to fix bugs that only occurred when using the same pass manager to compile multiple modules (generally these bugs are failure to reset some persistent state). Unfortunately I don't think there is currently a way to test that from the command line. This adds a very simple flag to both llc and opt, under which the tools will simply re-run their respective pass pipelines using the same pass manager on (a clone of the same module). Additionally, we verify that both outputs are bitwise the same.
