Add a constant cost function to the autodiff benchmarks

The constant cost function is run with a variable number of
parameters to test at which point, different compilers fail
to optimize the autodiff code.

Clang achieves expected performance which fails at >50 parameters.
G++ fails already at 20 parameters

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
