Hm, it'd have been nice to get that feedback a little bit earlier, I did
inquire...

Currently:

JIT:
  Functions: 2
  Generation Time: 0.680 ms
  Inlining: true
  Inlining Time: 7.591 ms
  Optimization: true
  Optimization Time: 20.522 ms
  Emission Time: 14.607 ms

How about making that:

JIT:
  Functions: 2
  Options: Inlining, Optimization
  Times (Total, Generation, Inlining, Optimization, Emission): 43.4 ms, 0.680 ms, 7.591 ms, 20.522 ms, 14.607 ms

or something similar?
