Since we are using the Scalarizer pass in the backend we needed a way to allow this pass to operate on Target intrinsics. We achieved this by adding `TargetTransformInfo ` to the Scalarizer pass. This allowed us to call a function available to the DirectX backend to know if an intrinsic is a target intrinsic that should be scalarized.
