Isn't it already an error? The intrinsic is defined in a way that requires a
vector:
```
def int_dx_length : DefaultAttrsIntrinsic<[LLVMVectorElementType<0>],
[llvm_anyfloat_ty]>;
```
That said I guess there is an argument that the crash on a vector of length 1
isn't ideal. Maybe we should make that an error as well.
