  Log Message:
  -----------
  [SLP]Change the order of the reduction/binops args pair vectorization attempts.

Need to change the order of the reduction/binops args pair vectorization
attempts. Need to try to find the reduction at first and postpone
vectorization of binops args. This may help to find more reduction
patterns and vectorize them.
