This reverts commit 959448fbd6.
Reverting because multiple test failures e.g.
https://lab.llvm.org/buildbot/#/builders/187/builds/1290
https://lab.llvm.org/buildbot/#/builders/153/builds/9389
and maybe a few others.

; Fix for PR33641. ArgumentPromotion removed the argument to bar but left the call to
|
|
; dbg.value which still used the removed argument.
|
|
|
|
; The %p argument should be removed, and the use of it in dbg.value should be
|
|
; changed to undef.
