If the openmp project is built standalone, the test compiler is feature tested for an available -fsanitize=thread flag.
If the openmp project is built as part of llvm, the target tsan is needed to test archer.
An additional line (requires tsan) was introduced to the tests, this patch updates the line numbers for the race.
