Printing pass manager invocations is fairly verbose and not super useful. This allows us to remove DebugLogging from pass managers and PassBuilder since all logging (aside from analysis managers) goes through instrumentation now. This has the downside of never being able to print the top level pass manager via instrumentation, but that seems like a minor downside.

; 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.
