This PR of course shouldn't be merged as-is because the submodule shound point to the merge commit in wasi-libc. |
This commit enables thread support in libc++ for all thread models, enabling C++ applications that use threading APIs like `<atomic>` but do not spawn threads (e.g. Clang) to be built with minimal changes. Fixes WebAssembly#546.

@alexcrichton I have compiled Clang with the current HEAD and it builds and runs fine. |

Thanks to recent wasi-libc changes, wasi-libc and libc++ in wasi-sdk now provides `std::atomic`, `std::mutex`, and other thread-related APIs even for wasm32-wasip1 target. * WebAssembly/wasi-libc#602 * WebAssembly/wasi-sdk#548
