This is the same exact change we did for the current pass manager in rL314997, but the new pass manager pipeline already happened to run GlobalOpt after the inliner, so we just insert a run of GDCE here. llvm-svn: 315003

; 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.
