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