Daco Harkes e418026d74 [vm/ffi] Support late Finalizable variables
This CL changes the IL building for reachability fences to their call
sites. This enables us to catch the field load and tell it to not emit
an initialization check for late fields.

The sentinel value will now flow into the ReachabilityFenceInstr, where
it will be discarded.
