With https://go-review.googlesource.com/10638, the reference counting of Go objects can be simplified. Everytime a Go object is passed into Objective-C side, a new proxy object with GoSeqRef is created. Deallocation of a GoSeqRef decrements the reference counter of the corresponding Go object. Test the Go object is collected. Note: It's possible to reduce the number of GoSeqRef allocations by maintaining a map of weak references to the existing GoSeqRef, but for now, we allocate a new GoSeqRef instance.
