  Changed paths:
    M llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp
    A llvm/test/Transforms/SLPVectorizer/X86/buildvector-same-lane-insert.ll

  Log Message:
  -----------
  [SLP]Do not look for buildvector sequence, if the index is reused.

If the insert indes was used already or is not constant, we should stop
looking for unique buildvector sequence, it mustbe splitted to
2 different buildvectors.
