CHPL_UNWIND=libunwind nightly testing about chapel

[mppf]

We should probably decide, as a matter of policy, if stack traces are expected in .good files, or if the prediff should handle the case that the .good file has no stack trace. If the stack traces are included in .good files, many more internal/standard module line numbers can be exposed, so we presumably need a way to handle that intelligently. It would not be an improvement to have to update every test that halts when certain internal module code is moved to different lines.

We now have a basic unwind.gasnet nightly testing that covers building the compiler with CHPL_UNWIND=bundled and basic stacktrace tests. Did you want to close this issue or keep it around to add more testing?

Thanks, I'll close it.
