clang-p2996/llvm/test/Transforms/SLPVectorizer/AArch64/vectorize-free-extracts-inserts.ll
Alexey Bataev b8703369da [SLP] Match poison as instruction with the same opcode 
Patch allows to vector scalar instruction + poison values as if poisons
are instructions with the same opcode. It allows better vectorization of
the repeated values, reduces number of insertelement instructions and
serves as a base ground for copyable elements vectorization
