make O0 default in test harness.

check openmp official example.

Thanks for reporting this issue. I notice -q option is not available commonly. We will re-evaluate if this option can be removed.

The reason for adding -q option is ThreadSanitizer reports exit code 66 by default. I remove the -q option, but need to add "exitcode=0" for ThreadSanitizer.

Add json file to include meta information for OMP version, pattern categories.
