clang-p2996/llvm/test/Transforms/InstCombine/vec_shuffle.ll
Sanjay Patel 42d31c20a8 [InstCombine] allow shuffle+binop canonicalization with widening shuffles 
This lines up with the behavior of an existing transform where if both 
operands of the binop are shuffled, we allow moving the binop before the 
shuffle regardless of whether the shuffle changes the size of the vector.
