   > @jianxind What is your opinion on the approach here?
   
   It's fine to introduce ARROW_RUNTIME_SIMD_LEVEL flag which give more user options. Another potential approach is the ARROW_USER_SIMD_LEVEL flag during runtime, something like "ARROW_USER_SIMD_LEVEL=avx2 make unittest", I'm not familiar with CI system thus don't know if it's easy to hook ARROW_USER_SIMD_LEVEL flag.
