While analyzing our big data Apps, we observed unexpected deoptimizations in loop exit due to incorrect branch profiling.

Here is a reproducer.
```
public class UnexpectedLoopExitDeopt {
    public static final int N = 20000000;

    public static int d1[] = new int[N];
    public static int d2[] = new int[N];

    public static void main(String[] args) {
        System.out.println(test(d1));
        System.out.println(test(d2));
    }

    public static int test(int[] a) {
        int sum = 0;
        for(int i = 0; i < a.length; i++) {
            sum += a[i];
        }
        return sum;
    }
}
```


The following is the compilation sequence.

```

The last two deopts (made not entrant) happened in the loop exit which are unexpected.
It would be better to to fix it.
