TPL Hangs on Error During Execution

[turingcompl33t]

In the event that execution of a TPL program fails (e.g. during interpretation, after a call to Module::GetFunction()) the tpl command-line program hangs after reporting the error. This is likely because of some state that gets corrupted which prevents the LLVM engine from shutting down or the TBB scheduler (the only two resources we attempt to clean up after a failure).

This error manifests when running TPL programs via the tpl command-line tool, but is also likely present in the DBMS itself.
