Refactor the automatic differentiation benchmarks.

1. Merge them into a single binary.
2. All benchmarks now do the Residual and the Residual + Jacobian
evaluation.
3. Re-organize and simplify the CMake file in this directory.
4. Fix a bug in the file where the Clang compiler was not being matched.
