> Roll src/buildtools/third_party/libc++/trunk/ d9040c75c..69897abe2 (1149 commits)
>
> It has been a long time since the last libc++ roll, so many extra
> changes were required:
> - New libc++ cpp files added to gn
> - Re-generated prebuilt gvr_shim for Android
> - Updated absl symbols for libc++ roll (crbug.com/1166430)
> - Updated static initializer expectations for second libc++ iostream
>   initializer
> - Disabled checked_iterator test relying on std::copy implementation
>   details (crbug.com/1166360)
> - Added global availability macro for crbug.com/1166707
> - Adjusted some pragma max_token limits for new headers
> - Overrode _LIBCPP_HIDE_FROM_ABI to work around crbug.com/1090975 on Windows
> - Defined _LIBCPP_NO_NATIVE_SEMAPHORES to work around crbug.com/1166970
