Reviewers: fschneider, Description: Introduce extra IC state to record additional feedback from IC-s.
Extra IC state is only two bits and only supported for call IC-s for now. To change its extra state an IC stub jumps to a new miss stub that goes to runtime as usual but then instead of going megamorphic generates a monomorphic stub with the updated state.
