  Changed paths:
    M llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp
    M llvm/test/Transforms/SLPVectorizer/X86/multi-node-vectorized-insts.ll

  Log Message:
  -----------
  [SLP]Do not gather node, if the instruction, that does not require
scheduling, is previously vectorized.

If the main node was vectorized already, but does not require
scheduling, we still can try to vectorize it in this new node instead of
gathering.
