Alex Stewart 8c36bcc81f Use inline & -inlinehint-threshold in auto-diff benchmarks 
- This results in the same performance as the original solution of
  increasing -inline-threshold, but this approach is more viable to
  incorporate in a large code base as its effects are more targeted.

Darius Rueckert 9f7fb66d62 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
