Miscellaneous backward autodiff fixes. (#2665)
* Fix differentiable type registration
* Fix use of non-differentiable return value in a differentiable func.
* Fix use of primal inst that does not dominate the diff block.
* Fix primal inst hoisting, and add missing type legalization logic.
* Make `detach` defined on all differentiable T.
