We tend to assume that the AA pipeline is by default the default AA pipeline and it's confusing when it's empty instead. PR48779 Initially reverted due to BasicAA running analyses in an unspecified order (multiple function calls as parameters), fixed by fetching analyses before the call to construct BasicAA.

; 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.
