34447efd - [clang][test] Specify value of `-fopenmp=libomp` for test. (#150301)

[clang][test] Specify value of `-fopenmp=libomp` for test. (#150301) `libomp` is the default value when unconfigured in cmake, but llvm can be configured to have `libgomp` be the default instead. Explicitly specify this value so the test does not fail when it assumes libomp is always the default.
