The recent commit adds a runtime test case this PR fixes, as well as moves the OMPMapInfoFinalization pass to work on a per module rather than per function basis to make sure it's performed sequentially, at least for the moment, as whilst there's no race conditions I am aware of at the moment, this pass undergoes a lot of maintenance/extension at the moment, so likely best to keep it simple until it stabilizes (for my own sanity as well as others).
