Test commit: https://github.com/llvm/llvm-project/commit/9e91725fd4d4ee30e98ab2682f93b423590a4ade
Steps to reproduce:
```shell
mlir-opt test.mlir -affine-super-vectorizer-test=vectorize-affine-loop-nest
```
Test case:
```mlir
#map = affine_map<(d0) -> (d0)>
#map1 = affine_map<(d0) -> (d0 + 1)>
module {
llvm.func @malloc(i32) -> !llvm.ptr
func.func @main(%arg0: tensor<4x4xf32>, %arg1: tensor<*xf32>, %arg2: tensor<*xf32>, %arg3: tensor<2x3xi32>, %arg4: tensor<2x3xi32>) attributes {llvm.emit_c_interface} {
%0 = llvm.mlir.constant(0 : index) : i64
%1 = llvm.mlir.constant(0 : index) : i32
%2 = llvm.mlir.poison : !llvm.struct<(ptr, ptr, i32, array<1 x i32>, array<1 x i32>)>
%3 = llvm.mlir.constant(64 : index) : i32
%4 = llvm.mlir.zero : !llvm.ptr
%5 = builtin.unrealized_conversion_cast %0 : i64 to index
%6 = bufferization.to_memref %arg0 : tensor<4x4xf32> to memref<4x4xf32, strided<[?, ?], offset: ?>>
%7 = llvm.getelementptr %4[4] : (!llvm.ptr) -> !llvm.ptr, f32
%8 = llvm.ptrtoint %7 : !llvm.ptr to i32
%9 = llvm.add %8, %3 : i32
%10 = llvm.call @malloc(%9) : (i32) -> !llvm.ptr
%11 = llvm.insertvalue %10, %2[0] : !llvm.struct<(ptr, ptr, i32, array<1 x i32>, array<1 x i32>)>
%12 = builtin.unrealized_conversion_cast %11 : !llvm.struct<(ptr, ptr, i32, array<1 x i32>, array<1 x i32>)> to memref<4xf32>
affine.for %arg5 = 0 to 4 {
affine.for %arg6 = #map(%arg5) to #map1(%arg5) {
%13 = affine.load %6[%arg6, %5] : memref<4x4xf32, strided<[?, ?], offset: ?>>
%14 = affine.load %12[%arg6] : memref<4xf32>
%15 = llvm.intr.minimum(%13, %14) : (f32, f32) -> f32
affine.store %15, %12[%arg6] : memref<4xf32>
}
}
