F27851102: test.ll <https://reviews.llvm.org/F27851102>

command to reproduce: opt -passes=slp-vectorizer -mtriple=x86_64 -mcpu=core-avx2 -S test.ll

BTW. which gcc version you use to build? I've experienced problem building with both 7.5.0 and 8.5.0 (I did not try any later versions) while there were no issues w/o patch.
Here is fail log:
<dir>/llvm-project/llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:3573:24: error: declaration of llvm::TargetTransformInfo* llvm::slpvectorizer::BoUpSLP::TTI [-fpermissive]

  TargetTransformInfo *TTI;
