When encountering a doc comment without an identifier after, we'd unconditionally state "this doc comment doesn't document anything", swallowing the *actual* error which is that the thing *after* the doc comment wasn't expected. Added a check that the found token is something that "conceptually" closes the previous item before emitting that error, otherwise just complain about the missing identifier.
In both of the following cases, the syntax error follows a doc comment:
```
error: expected identifier, found keyword `Self`
--> $DIR/doc-before-bad-variant.rs:4:5
|
LL | enum TestEnum {
| -------- while parsing this enum
...
LL | Self,
| ^^^^ expected identifier, found keyword
|
= help: enum variants can be `Variant`, `Variant = <integer>`, `Variant(Type, ..., TypeN)` or `Variant { fields: Types }`
```
```
error: expected identifier, found `<`
--> $DIR/doc-before-syntax-error.rs:2:1
|
LL | <>
| ^ expected identifier
```
Fix #71982.
