All of these methods have 7 int parameters.

Inlining is not marked as NoInlining, the rests are marked as NoInlining.

Hook0 is hooked by a hook that don't call orig.

CORRECTION: it doesn't even accept orig. MonoMod has optimization for this case.

CORRECTION: the said optimization is failed.

ILHook is ilhooked.

Hooked is hooked previously. It's not hooked when benchmarking.
