After LLVM moved to C++14, the RWMutex implementation was removed in favor of std::shared_timed_mutex, which is only available on macOS 10.12 and later. As a workaround for older deployment targets, I added the original RWMutexImpl again, guarded by the deployment target. When doing a standalone build of LLDB using the Xcode generator, the CMake cache specifies a minimum deployment target. However, LLVM and Clang might have been built with a different minimum deployment target. This is exactly what happened for the Xcode build. LLVM was built with a minimum deployment target newer than 10.12, using std::shared_timed_mutex. LLDB on the other hand was built with a minimum deployment target of 10.11, using the old RWMutexImpl, resulting in undefined symbols at link-time. This patch changes the minimum deployment target for the Xcode build to 10.12 to work around this problem. A better solution would involve synchronizing the minimum deployment or even not setting one at all. llvm-svn: 369220
