[Attributor][FIX] Do not ignore memory writes in AAMemoryBehavior

Even if we look for `nocapture` we need to bail on escaping pointers.
The crucial thing is that we might not look at a big enough scope when
we derive the memory behavior. Thus, it might be `nocapture` in a larger
context while it is "captured" in a smaller context.

[Attributor][NFX] Pre-commit test case exposing a problem

The test case is the IR of:

```
  void func(float * restrict a, float *b, int N) {
    N = 199;
    #pragma omp parallel for
    for (int i = 1; i < N; i++)
      a[i] = b[i] + 1.0;
  }
```
