looks like these changes break the llvm configuration when `openmp` is a part of `LLVM_ENABLE_PROJECTS`, but not in `LLVM_ENABLE_RUNTIMES`. It tries to create new build targets with already existing names.
```
  add_library cannot create target "llvm_gtest" because another target with
  the same name already exists.  The existing target is a static library
  created in source directory
  ```
 and
 ```
  add_library cannot create target "llvm_gtest_main" because another target
  with the same name already exists.  The existing target is a static library
  created in source directory
