[clang-format] AlignConsecutiveAssignments aligns = in operator= with =delete. 

clang-format config:
```
AlignConsecutiveAssignments: true
```

With otherwise default options aligns the equal sign in `operator=` with the equal sign that deletes the copy assignment operator: 

```
struct F {
  void operator=(F const &) = delete;
  void operator             =(F &&) {
    // stuff
  }
};
```
