3b0d1599ad C#: Teach guards library about unique assignments
For example, in

```
void M(object x)
{
    var y = x == null ? 1 : 2;
    if (y == 2)
        x.ToString();
}
```

the guard `y == 2` implies that the guard `x == null` must be false,
as the assignment of `2` to `y` is unique.

ab9aa7d338 C#: Teach guards library about conditional assignments
For example, in

```
void M(object x)
{
    var y = x != null ? "" : null;
    if (y != null)
        x.ToString();
}
```

the guard `y != null` implies that the guard `x != null` must be true.
