Await.NextUpdate() crashes on Android IL2CPP

[bschug]

If you run await Await.NextUpdate() on Android, it will fail with Unable to create field getter for Object.m_CachedPtr; internal implementation may have changed.. The stacktrace appears to be corrupted.

I expected this to be fixed in 15ee6b1. It should avoid all reflection and expressions when compiling with IL2CPP.
I don't work with Android builds very often so I haven't actually tested the fix but I'm downloading the Android modules now to see if I can test it.
