  -----------
  [clang-format] Recognize TableGen paste operator on separate line (#133722)

Formatting this piece of code made the program crash.

```
class TypedVecListRegOperand<RegisterClass Reg, int lanes, string eltsize>
    : RegisterOperand<Reg, "printTypedVectorList<" # lanes # ", '"
                                                   # eltsize # "'>">;
```

The line starting with the `#` was treated as a separate preprocessor
directive line. Then the code dereferenced a null pointer when it tried
to continue parsing the first line that did not end in a semicolon.

Now the 2 problems are fixed.
