* Move muliti-functionality SIL tests to test/AutoDiff/SIL. * Add `with_derivative` clause to `differentiable_function` instructions. Otherwise, IRGen for test/AutoDiff/SIL/differentiable_function_inst.sil fails on tensorflow branch because the differentiation transform cannot differentiate external functions.
