MonoModBenchmark

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 does not exist. and, even if it exists, as the hook method is not static, it would failed.

ILHook is ilhooked.

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