What about `dxil::ElementType::I64`? 

We could arguably pre-emptively put `SNormF64` and `UNormF64` in here too (They also use `U32` - https://hlsl.godbolt.org/z/3jr3qG17q), but I don't think we can really test that so it's probably fine to leave it as a TODO until the `toDXILElementType` TODO is completed.
