This would allow us to emit code optionally when needed (e.g. sampler) and would be much faster.
Compiling native stubs not only advantages monacle by controlling how they are compiled, it reduces player static footprint, and it allows embedding AvmCore* as a constant in the stub, which improves performance. Finally, it gives the JIT total control over JIT calling conventions, which will help with OSR/DEOPT and callee-saved register issues.
