Now that we've branched for the LLVM 14 release, our support window moves to clang-13 and clang-14. Similarly, AppleClang 13 has been released for some time now, so that should be the oldest compiler we support, per our policy. A possible follow-up would be to remove _LIBCPP_HAS_NO_CONCEPTS, since I don't think we support any compiler that doesn't support concepts anymore.
