minify-dead-code-elimination incorrectly removes return statement in a loop

[asapach]

Simplified repro:

function remove(id) {
    for (var j = 0; j < array.length; ++j) {
        if (array[j] === id) {
            array.splice(j, 1);
            return;
        }
    }
}

Output:

function remove(id) {
    for (var j = 0; j < array.length; ++j) {
        if (array[j] === id) {
            array.splice(j, 1);
        }
    }
}

In this case return is not dead code, since it terminates the loop. Interestingly break statement is not removed in the similar case.
