(852445) - IL2CPP: Added proper support for a class that is marshalled as a field of another class or struct, including the proper return value for a call to Marshal.Sizeof in this case.

(846956) - IL2CPP: Added support for managed stack traces on Android.

(849701) - IL2CPP: Corrected a crash that can occur in the player when a virtual method is called on a value type and that value type implements an interface which has an overload of that virtual method.

(845666) - IL2CPP: Corrected managed stack traces when Xcode 8 is used to build on iOS with link-time optimization enabled.
