[PATCH] D131274: [clang][Darwin] Re-apply "Always set the default C++ Standard Library to libc++"

[Louis Dionne via Phabricator via cfe-commits]

ldionne updated this revision to Diff 451287.
ldionne added a comment.

Fix more tests that failed on internal bots (but I can't reproduce the failure 
locally for some reason)
