[clang-format] binary expression is reformatted as pointer declaration

[isuckatcs]

int A = 1, B = 2;

int main() {
  A * B;

  return 0;
}

In the snippet above clang-format would reformat the A * B expression as A *B, which visually implies a pointer declaration.

See the example on godbolt.

```c++ int A = 1, B = 2;

int main() {
A * B;

return 0;
}

In the snippet above clang-format would reformat the `A * B` expression as `A *B`, which visually implies a pointer declaration.

AFAIK, clang-format always treats this as a declaration.
