Collect all unreachable fields in a single struct literal struct and emit a single error, instead of one error per private field.
```
error[E0451]: fields `beta` and `gamma` of struct `Alpha` are private
--> $DIR/visibility.rs:18:13
|
LL | let _x = Alpha {
| ----- in this type
LL | beta: 0,
| ^^^^^^^ private field
LL | ..
| ^^ field `gamma` is private
