Fixes #145511 Note that there are still two instances of --passes=slp-vectorizer,instcombine left unchanged because it seems that the tests are meant to run in conjunction with instcombine and removing instcombine would invalidate their original objective: [llvm/test/Transforms/SLPVectorizer/arith-div-undef.ll](https://github.com/llvm/llvm-project/blob/main/llvm/test/Transforms/SLPVectorizer/arith-div-undef.ll) [llvm/test/Transforms/SLPVectorizer/slp-hr-with-reuse.ll](https://github.com/llvm/llvm-project/blob/main/llvm/test/Transforms/SLPVectorizer/slp-hr-with-reuse.ll)
