I have the following MLIR program:
test.mlir:
```
module {
func.func @func1() {
%idx0 = index.constant 0
%alloc_82 = memref.alloc() : memref<1xi64>
affine.for %arg0 = 0 to 78 {
%dim_191 = memref.dim %alloc_82, %idx0 : memref<1xi64>
}
return
}
}
```
The above MLIR program will cause a crash when using the following command:
```
mlir-opt --affine-super-vectorize="virtual-vector-size=128" test.mlir
```
And the crash backtrace is:
```
<unknown>:0: error: failed to verify 'elementType': integer or index or floating-point
mlir-opt: /data/tmp/v0222/llvm-project/mlir/include/mlir/IR/StorageUniquerSupport.h:179: static ConcreteT mlir::detail::StorageUserBase<ConcreteT, BaseT, StorageT, UniquerT, Traits>::get(mlir::MLIRContext*, Args&& ...) [with Args = {llvm::ArrayRef<long int>&, mlir::Type&, llvm::ArrayRef<bool>&}; ConcreteT = mlir::VectorType; BaseT = mlir::Type; StorageT = mlir::detail::VectorTypeStorage; UniquerT = mlir::detail::TypeUniquer; Traits = {mlir::ShapedType::Trait, mlir::ValueSemantics}]: Assertion `succeeded( ConcreteT::verifyInvariants(getDefaultDiagnosticEmitFn(ctx), args...))' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
