> Thanks to the new kernel framework, now it can override a SIMD kernel version at runtime.
>  
> Below is the things we need implemented for a SIMD version of sum kernel :
> 1. Add SIMD path for aggregate sum dense.
>  2. Add build support to append the compiler flag for SIMD code file.
>  3. Register the SIMD version at runtime as the CPU feature.
