SR-7708 labeled do statement can be looped with continue

Issue Description:

In Swift5.5, this code just works, and prints 0 to 9.

var count = 0
loop: do {
    print(count)
    count += 1
    if count >= 10 {
        break loop
    }
    continue loop
}

Since unlabeled `do` doesn't allow `continue`, I suspect this is remnant of era when `do-while` was used. It seems incorrect behavior today.
