; The IR below was crafted so as:
; 1) To have a loop, so we create a loop pass manager
; 2) To be "immutable" in the sense that no pass in the standard
; pipeline will modify it.
; Since no transformations take place, we don't expect any analyses
; to be invalidated.
; Any invalidation that shows up here is a bug, unless we started modifying
; the IR, in which case we need to make it immutable harder.
