| Summary |
[MLIR] crash in `-affine-super-vectorizer-test="vector-shape-ratio=4,8"` due to violation of the assertion `(ratio || !mustDivide) && "vector.transfer operation in which super-vector size is not an" " integer multiple of sub-vector size"'

test commit: [66da9f38f](https://github.com/llvm/llvm-project/commit/66da9f38f374e786b2f1c0ecdab0b651c94c4f27)
Step to reproduce:
```
mlir-opt test.mlir --affine-super-vectorizer-test="vector-shape-ratio=4,8"
```
test case:
```
module attributes {test.block_ids = array<i64: 13>} {
func.func @main(%arg0: tensor<82x97xi64>, %arg1: tensor<1x97xi64>) {
%0 = ub.poison : i64
%alloc = memref.alloc() {alignment = 64 : i64} : memref<82x97xi64, #spirv.storage_class<StorageBuffer>>
affine.for %arg2 = 0 to 82 {
affine.for %arg3 = 0 to 97 step 128 {
%1 = vector.transfer_read %alloc[%arg2, %arg3], %0 : memref<82x97xi64, #spirv.storage_class<StorageBuffer>>, vector<128xi64>
}
}
return
}
}
```
Crash backtrace:
```
mlir-opt: /home/workdir/llvm-project/mlir/lib/Dialect/Vector/Utils/VectorUtils.cpp:247: bool mlir::matcher::operatesOnSuperVectorsOf(Operation &, VectorType): Assertion `(ratio || !mustDivide) && "vector.transfer operation in which super-vector size is not an" " integer multiple of sub-vector size"' failed.
