[PATCH] D21968: [libcxx] Externally threaded libc++ variant - Take 2

[Marshall Clow via cfe-commits]

mclow.lists added a comment.

The patch (again) doesn't apply cleanly (test/CMakeLists.txt), so I applied it manually.
After that, it builds w/o errors, and passes all the tests.

After addressing @EricWF's concerns, I think this is ready to land.
