  -----------
  [SLP]Initial non-power-of-2 support (but still whole register) for reductions

Enables initial non-power-of-2 support (but still requires number of
elements, forming whole registers) for reductions.
Enables extra vectorization for
MultiSource/Benchmarks/7zip/7zip-benchmark, CINT2006/464.h264ref and
CFP2017rate/526.blender_r (checked for SSE2)
