<pre>
    The OpenMP tests on Windows don't pass successfully. Using latest Visual Studio 17.8.3 on Windows 11 version 23H2. Using LLVM commit 6c2fbc3a68ba6d4bd1c8c2c43c98cff5e82f2ba4. I am including a branch below with an easy repro.

Just open an elevated admin `cmd.exe` and run the following.
```
C:\git>git clone https://github.com/aganea/llvm-project.git
...
C:\git>cd llvm-project && git switch bugreport_openmp_tests && cd ..
...
C:\git>llvm-project\llvm\utils\release\build_llvm_release.bat --version 18.0.0 --x64
