Test on commit: https://github.com/llvm/llvm-project/commit/01cc1d13cd0c54bd4c29185b052fa5c16285dca7
steps to reproduce:
```
build/bin/mlir-opt test.mlir --test-options-pass --test-loop-permutation="permutation-map=1,0,2" --affine-super-vectorizer-test=compose-maps --verify-each=false --test-extract-fixed-outer-loops='test-outer-loop-sizes=7,4' --test-tensor-transform-patterns=test-reassociative-reshape-folding
```
test case:
```
func.func @reduce_sum(%buffer: memref<1024xf32>, %lb: index,
%ub: index, %step: index) {
%initial_sum = arith.constant 0.0 : f32
%final_sum = scf.for %iv = %lb to %ub step %step
iter_args(%sum_iter = %initial_sum) -> (f32) {
%element = memref.load %buffer[%iv] : memref<1024xf32>
%updated_sum = arith.addf %sum_iter, %element : f32
scf.yield %updated_sum : f32
}
return
}
```
