      Our recent runs on different leading edge platforms show that Floating point reduction kernels are better off SLP vectorization than with SLP.

      While ADD MUL shows degraded performance on Granite Rapids AP.
      Min/Max shows performance degradation on Sierra Forest SP (AVX2 only Xeon)

      Please find attached the data.
