LGTM except a minor issue.



================
Comment at: libcxx/src/support/win32/thread_win32.cpp:250
+  // round-up to the nearest millisecond
+  chrono::milliseconds __ms = std::chrono::ceil<chrono::milliseconds>(__ns);
   // FIXME(compnerd) this should be an alertable sleep (WFSO or SleepEx)

I think we should use `std::` in the `src` directory. For consistency I'd like to remove the `std::` here. The function argument also uses `chrono` instead of `std::chrono`. Maybe also adjust `__libcpp_semaphore_wait_timed` so they are similar.
