[PATCH] D62831: [CodeGen][ObjC] Add attribute "arc_retain_agnostic" to ObjC globals that are retain-agnostic

[Erik Pilkington via Phabricator via cfe-commits]

I think this looks good from a clang perspective. No reason to land it before the dust settles on D62433 <https://reviews.llvm.org/D62433> though.

Do you think we can also add this attribute (or something like it) onto allocas of `_NSConcreteStackBlock`s? They also have this retain-swallowing behaviour.
