Yep, it was completely my fault. I specified the wrong path to my opt binary, so runPassesOn() silently failed with 'file not found'. I added a warning: http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20180205/523911.html.

But.. I haven't devoted any time to figuring out why the bugpoint invocation in unsymbolized.ll hit the "exit(1)" path before this change. I'll need to figure that out before landing this.
