[PATCH] D43787: Fix which Darwin versions have ObjC runtime with full subscripting support.

[Volodymyr Sapsai via Phabricator via cfe-commits]

vsapsai created this revision.
vsapsai added reviewers: vsk, kubamracek.
Herald added a subscriber: jkorous-apple.

Update min deployment target in some tests so that they don't try
to link against libarclite and don't fail when it's not available.
