Jan Voung 6f659b0060 [clang][dataflow] For bugprone-unchecked-optional-access report range (#131055) ...

Report the range in diagnostics, in addition to the location
in case the range helps disambiguate a little in chained `->`
expressions.
```
b->a->f->x = 1;
^~~~~~~
```
instead of just:
```
b->a->f->x = 1;
^
```
As a followup we should probably also report the location/range
of an `->` if that operator is used. Like:
```
b->a->f->x = 1;
       ^~
```
