fix: not suggest seek_to_start_instead_of_rewind when expr is used
changelog: [`seek_to_start_instead_of_rewind`]: No longer lints, if the return of `seek` is used.
[#10096](https://github.com/rust-lang/rust-clippy/pull/10096)
<!-- changelog_checked -->
Fixes#10065
There used to be a logical bug where IncrementVisitor would
completely stop checking an expression/block after seeing a continue
statement. This led to issue #10058 where a variable incremented
(or otherwise modified) after any continue statement would still be
considered incremented only once.
The solution is to continue scanning the expression after seeing a
`continue` statement, but increment self.depth so that the Visitor
thinks that the rest of the loop is within a conditional.
Cleanup `rustc_tool_util` and add a convenient macro for `build.rs`

<!-- changelog_checked -->
If possible, I'd like to have a new release for this, maybe `v0.3.0` to use the changes in another project. Then we can also remove the `path = "./rustc_tools_util"` from `Cargo.toml`. I'd be happy to help with the release on crates.io if you'd like the help :)

improve `manual_is_ascii_check ` check
Sorry, not familiar the api, i can only check the method name of expression `<expr-1>.contains(<expr-2>)` after read clippy book and hints from #9933 . i dont know how to check
1. if <expr-1> is a specific range
2. <expr-2> is a character
r? `@xFrednet` could you please provide some more hints? 😝️

add `suppress_restriction_lint_in_const` config
According to #9808 , add a new lint `suppress_lint_in_const` to report even in const context. BTW, i am not good at naming either, if anyone have a better idea, i am happy to change it.
This PR is still in progress, so i keep it draft.

Fix 10021
This PR proposes a fix for #10021.
The problem is similar to the one that `@mikerite` described in #9505. The compiler is generating an empty substitution for a call, even though the type of `Self` seems to be needed for a predicate. In `@mikerite's` case, the call was to [`IntoFuture::into_future`](https://doc.rust-lang.org/std/future/trait.IntoFuture.html#tymethod.into_future). In this case, the call is to [`Try::branch`](https://doc.rust-lang.org/std/ops/trait.Try.html#tymethod.branch).
The proposed fix is to verify that the parameter whose type is changing has an index within the substitution. The strikes me as a reasonable approach, since if the check were to fail, the following code would be a no-op:
4c123a06ba/clippy_lints/src/methods/unnecessary_to_owned.rs (L420-L428)
Like `@mikerite's` original solution, this solution turns ICEs into false negatives.
