[JR Cary via Openmp-dev]

Building openmp-r350157 with the trunk (r350156) of clang-cl fails.

Configured with
'/winsame/test/contrib-clang_vs2017/cmake-3.10.3-ser/bin/cmake' \
-DCMAKE_INSTALL_PREFIX:PATH=D:/winsame/test/volatile-clang_vs2017/llvm-r350156-ser

Build fails with two errors:

D:\winsame\cary\llvmall\openmp\runtime\src\z_Windows_NT_util.cpp(327,38): 
error: call to deleted constructor of 'std::atomic<unsigned int>'^M
                th_gtid, flag->get(), *(flag->get())));^M
                                      ^~~~~~~~~~~~~~^M

D:\winsame\cary\llvmall\openmp\runtime\src\z_Windows_NT_util.cpp(435,62):

                    gtid, target_gtid, flag->get(), old_spin,

any suggestions much appreciated.
