Thanks for letting me know, didn't notice you had already worked on this, thanks! this branch is based on a past build - guess I oughta rebase.

Based on  some grepping around the codebase, external init is not exclusive to CUDA. So I think renaming it and defining it on `CIRAttrs.td` its the right call.
