test commit: [66da9f38f](https://github.com/llvm/llvm-project/commit/66da9f38f374e786b2f1c0ecdab0b651c94c4f27)
Step to reproduce:
```
mlir-opt test.mlir --convert-vector-to-llvm
```
test case:
```
module {
llvm.func @malloc(i64) -> !llvm.ptr
func.func @main(%arg0: tensor<14x62x54xi8>, %arg1: tensor<f32>) {
%cst = arith.constant dense<false> : vector<128xi1>
%0 = llvm.mlir.poison : vector<128xi8>
%1 = llvm.mlir.constant(0 : i32) : i32
%2 = llvm.mlir.poison : vector<128xi32>
%3 = llvm.mlir.zero : !llvm.ptr
%4 = llvm.mlir.constant(62 : index) : i64
%cst_0 = arith.constant dense_resource<__elided__> : vector<128xi32>
%5 = llvm.mlir.constant(dense<1> : vector<128xi8>) : vector<128xi8>
affine.for %arg2 = 0 to 54 {
affine.for %arg3 = 0 to 62 step 128 {
%6 = builtin.unrealized_conversion_cast %arg3 : index to i32
%7 = builtin.unrealized_conversion_cast %arg3 : index to i64
%8 = spirv.ISub %1, %6 : i32
%9 = llvm.insertelement %8, %2[%1 : i32] : vector<128xi32>
%10 = vector.extract_strided_slice %9 {offsets = [0], sizes = [4], strides = [1]} : vector<128xi32> to vector<4xi32>
%11 = vector.extract_strided_slice %cst_0 {offsets = [0], sizes = [4], strides = [1]} : vector<128xi32> to vector<4xi32>
%12 = spirv.SGreaterThan %10, %11 : vector<4xi32>
%13 = vector.insert_strided_slice %12, %cst {offsets = [0], strides = [1]} : vector<4xi1> into vector<128xi1>
%14 = llvm.getelementptr %3[%4] : (!llvm.ptr, i64) -> !llvm.ptr, i8
llvm.intr.masked.store %5, %14, %13 {alignment = 1 : i32} : vector<128xi8>, vector<128xi1> into !llvm.ptr
}
}
return
}
}
