The `@llvm.dx.handle.fromBinding` intrinsic is lowered either to the `CreateHandle` op or a pair of `CreateHandleFromBinding` and `AnnotateHandle` ops, depending on the DXIL version. Regardless of the DXIL version we need to emit metadata about the binding, but that's left to a separate change. These DXIL ops all need to return the `%dx.types.Handle` type, but the llvm intrinsic returns a target extension type. To facilitate changing the type of the operation and all of its users, we introduce `%llvm.dx.cast.handle`, which can cast between the two handle representations.
