  Log Message:
  -----------
  [SLP]Improve vectorization of the CmpInst instructions.

During vectorization better to postpone the vectorization of the CmpInst
instructions till the end of the basic block. Otherwise we may vectorize
it too early and may miss some vectorization patterns, like reductions.
