Run rustfix for string_lit_as_bytes tests
This moves the `string_lit_as_bytes` tests into a new file and enables
rustfix tests for them.
cc #3603, #2038
Fix `boxed_local` suggestion
Don't warn about an argument that is moved into a closure.
ExprUseVisitor doesn't walk into nested bodies so use a new
visitor that collects the variables that are moved into closures.
Fixes#3739
* Ran automatic naming update
* Formalized rename of `cyclomatic_complexity` to `cognitive_complexity`
** Added the rename to `lib.rs`
** Added rename test
* Added warning for deprecated key `cyclomatic_complexity_threshold` and tests for it
* Added deprecation status for Clippy's builtin attribute
* Updated tests for new builtin attribute renaming
Fix `bool_comparison` with non-`bool` expressions
Fixes#3703.
It just moves around the type check that was already there for some comparison to all of them, because if one type isn't `bool`, none of those comparison can be simplified.
Fix ICE #3719+#3718 in lint match_ref_pats
Fixes#3719
This conveniently also fixes#3718
The ICE occurs when the match expression was a macro call, where the macro was defined in another file. Since we don't have the ability to reproduce this behavior with our UI tests (AFAIK), I couldn't add a test reproducing this ICE.. However, I added a test which is related to the ICE, to show the new behavior of the lint.
I tested it with the mscheme repo locally and the ICE didn't happen anymore.

Fix ICE #3747
I'm not sure if this was the correct approach.
I don't know if I put tests/ui/crashses/ice-3747.rs in correct place because the test always passed when I ran it with `cargo test`, even without the fix applied.
If I run that test with `env CLIPPY_TESTS=true cargo run --bin clippy-driver -- -L ./target/debug tests/ui/crashes/ice-3747.rs` then the test correctly fails without the fix applied
fixes#3747
Many people run rustfmt automatically on save. Format-dependent tests
should be marked with `#[rustfmt::skip]` to prevent accidental
reformatting from this. As a bonus the rest of the code can the formatted.
Make needless_range_loop not applicable to structures without iter method
Fixes https://github.com/rust-lang/rust-clippy/issues/3788
Now we will start lint indexed structure only if it has known iter or iter_mut method implemented.
Don't warn about an argument that is moved into a closure.
ExprUseVisitor doesn't walk into nested bodies so use a new
visitor that collects the variables that are moved into closures.
Fixes#3739
Don't check [print/write]_with_newline on raw strings
Some tests for #3778 and some maybe-not-the-greatest code that passes those tests!
I didn't run `fmt` because a) it doesn't seem to install on nightly for me, and b) on stable it wanted to apply formatting to over 90 files. Happy to make any tweaks though!
I suspect this contribution may require more than just tweaks. I'm still sort of new to rust so it may not be idiomatic, and the specific approach I took feels a little heavy-handed and brittle. I'm happy to make changes with some guidance, or equally happy if this gives a starting place for someone else to do it better :)
