Coroutines generate garbage in MoveNext
Coroutine::MoveNext causes the return value (a bool) to be boxed, which causes an allocation.
Reproduction Steps:
1. Run the attached project
2. Open the Profiler and sort by GC Alloc
3. Observe that FlagEndOfFrame is allocated 17B of garbage every frame
Expected Result:
It should be possible to run a coroutine without generating any garbage at all.

Also seen in 5.3.4f1. For any project using a lot of coroutines, this is a lot of garbage.
