> 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 SSE version of sum kernel to
> dense data:
> 1. Add SSE intrinsic path for aggregate sum dense.
> 2. Add build support to append the compiler flag for SIMD code file.
> 3. Register the SSE version at runtime as the CPU feature.
