; This test is essentially doing very basic things with the opt tool and the
; new pass manager pipeline. It will be used to flesh out the feature
; completeness of the opt tool when the new pass manager is engaged. The tests
; may not be useful once it becomes the default or may get spread out into other
; files, but for now this is just going to step the new process through its
; paces.
