BUG: CC0022 DisposableVariableNotDisposedAnalyzer: False positive in iterator methods

#Bug

This should not trigger CC0022:

public IEnumerable<IDisposable> Foo()
{
    var disposable = new MemoryStream();
    yield return disposable;
}

This works:

public IDisposable Foo()
{
    var disposable = new MemoryStream();
    return disposable;
}
