rustc: use more correct span data in for loop desugaring
Fixes#82462
Before:
help: consider adding semicolon after the expression so its temporaries are dropped sooner, before the local variables declared by the block are dropped
|
LL | for x in DroppingSlice(&*v).iter(); {
| +
After:
help: consider adding semicolon after the expression so its temporaries are dropped sooner, before the local variables declared by the block are dropped
|
LL | };
| +
This seems like a reasonable fix: since the desugared "expr_drop_temps_mut" contains the entire desugared loop construct, its span should contain the entire loop construct as well.

Add new lint `iter_not_returning_iterator`
Add new lint [`iter_not_returning_iterator`] to detect method `iter()` or `iter_mut()` returning a type not implementing `Iterator`

Allow giving reasons for `disallowed_methods`
Fixes#7609.
This permits writing the config for `disallowed-methods` as either a list of strings (like before) or a list of tables, where each table gives the path to the disallowed method and an optional reason for why the method is disallowed.

`mut_range_bound` check for immediate break after mutation
closes#7532
`mut_range_bound` ignores mutation on range bounds that is placed immediately before break. Still warns if the break is not always reachable.
changelog: [`mut_range_bound`] ignore range bound mutations before immediate break
Avoid slice indexing in Clippy (down with the ICEs)
While working on #7569 I got about 23 lint reports where we can avoid slice indexing by destructing the slice early. This is a preparation PR to avoid fixing them in the lint PR. (The implementation already takes about 300 lines without tests 😅). Either way, this should hopefully be easy to review 🙃
