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
