The generated IL2CPP code no longer Marshals a Struct to its Native Representation before passing it to a Native Function
To reproduce:
1. Download attached project "IL2CPPMarshalling.zip" and open in Unity
2. Open "Main" scene
3. Build for iOS
4. In the generated iOS Build folder under Classes > Native open "Bulk_Assembly-CSharp_0.cpp"
5. Search for "SendHandle"
6. Observe that IL2CPP code no longer performs a Marshaling step to Native Representation
