When lowering a destructuring assignment from AST to HIR, the compiler
will reuse the same identifier name (namely `sym::lhs`) for all the
fields. The desugaring must be checked for to avoid a false positive of
the `shadow_unrelated` lint.

assignments

will reuse the same identifier name (namely `sym::lhs`) for all the
fields. The desugaring must be checked for to avoid a false positive
of the `shadow_unrelated` lint.
Dereferencing string literals in suggestions is redundant.

string literals now

This extra condition prevents a problem when removing the '}' in:
```rust
( // There was an opening bracket after the parenthesis, which has been removed
// This is a comment
})
```
Removing the whitespaces, including the linefeed, before the '}', would
put the closing parenthesis at the end of the `// This is a comment`
line, which would make it part of the comment as well. In this case, it
is best to keep the span on the '}' alone.

Note to reviewer: `manual_inspect` and `collapsible_if` were two lints
exhibiting this problem in cooked up test cases, which have been
included as non-regression tests.

This PR enables the new ability to collapse `if` statements containing
comments (without losing them) in Clippy sources, excluding tests and
lintcheck, where the default behaviour (no collapsing in presence of
comments) is preserved.
To be applied after #14231. When it is applied, #14455 will be marked as
ready for review, then #14228 afterwards.

Both lints share a lot of characteristics but were implemented in
unrelated ways. This unifies them, saving around 100 SLOC in the
process, and making one more test trigger the lint. Also, this removes
useless blocks in suggestions.

The `uninlined_format_args` was temporarily downgraded to `pedantic` in
part because rust-analyzer was not fully supporting it at the time, per
#10087. The support has been added over [a year
ago](https://github.com/rust-lang/rust-analyzer/issues/11260), so seems
like this should be back to style.
Another source of the initial frustration was fixed since then as well -
this lint does not trigger by default in case only some arguments can be
inlined.

This PR does two things:
- It renames `inconsistent_struct_constructor`'s configuration from
`lint-inconsistent-struct-field-initializers` to
`check-inconsistent-struct-field-initializers`. (I should have suggested
`check-...` in
[#13737](https://github.com/rust-lang/rust-clippy/pull/13737#discussion_r1875118516).)
- It causes Clippy to no longer suggest deprecated configurations.
(Previously, Clippy would suggest `cyclomatic-complexity-threshold`, for
example.)

In the current GitHub Actions CI/CD setup, the `deploy` job is not
triggered when a PR is enqueued in the merge queue but only when it is
merged. Since concurrency is not configured for this job, deployments
may fail for later PRs if multiple PRs are merged in quick succession.
(e.g. the deployment for [this
commit](c418714518)
was successful, but the deployment for [this
commit](0a141ab7b8)
that was pushed to `main` immediately afterward failed. (edit: the
latter deployment seems to be rerun))

Replace the use of `Sugg::ast()` which prevented combining `if` together
when they contained comments by span manipulation.
A new configuration option `lint_commented_code`, which is `true` by
default, allows opting out from this behavior.
If reviewed on GitHub, the second commit of this PR is best looked at
side by side, with whitespace differences turned off.
changelog: [`collapsible_if`]: lint more cases
In #14116 we added a benchmarking option for Lintcheck, this commit adds
a new chapter to the book AND improves that option into a more usable
state.
It's recommended to review one commit at a time.
- **Document how to benchmark with lintcheck --perf**
- **Several improvements on lintcheck perf (desc.)**
- Now lintcheck perf deletes target directory after benchmarking,
benchmarking with a cache isn't very useful or telling of any
precise outcome.
- Support for benchmarking several times without having to do
a cargo clean.
- Compress perf.data
