Add lint for float in array comparison
Fixes#4277
changelog:
- Added new handler for expression of index kind (e.g. `arr[i]`). It returns a constant when both array and index are constant, or when the array is constant and all values are equal.
- Trigger float_cmp and float_cmp_const lint when comparing arrays. Allow for comparison when one of the arrays contains only zeros or infinities.
- Added appropriate tests for such cases.
Refactor: Use rustc's `match_def_path`
This replaces our match_def_path implementation with the rustc one.
Note that we can't just use it in all call sites because of the
`&[&str]` / `&[Symbol]` difference in Clippy/rustc.

Make use of more diagnostic items
This makes use of some (not all) already existing diagnostic items. Specifically:
* 79982a2: `core::mem::uninitialized`, `core::mem::zeroed`, `alloc::sync::Arc`, `alloc::sync::Rc`
* 83874d0: `Option` and `Result`

Fixes#5405: redundant clone false positive with arrays
Check whether slice elements implement Copy before suggesting to drop
the clone method
changelog: add a check for slice indexing on redundant_clone lint
Update documentation for new_ret_no_self
changelog: Update documentation for lint new_ret_no_self to reflect that the return type must only contain `Self`, not be `Self`
The lint was changed to be more lenient than the documentation implies in PR #3338 (Related issue #3313)
Change the existing hex bit mask (`0x1111`) to a binary one (`0b1111`).
The former does not seem to have anything to do with trailing zeros and is
probably a typo.
Allow UUID style formatting for `inconsistent_digit_grouping` lint
This change adds a check to the `inconsistent_digit_grouping` to add a check for
NumericLiterals that follow the UUID format of 8-4-4-4-12.
If the NumericLiteral matches the UUID format, no further inconsistent grouping checks
will be performed.
Closes#5431

Check for clone-on-copy in argument positions
Earlier if arguments to method calls matched the above pattern they were
not reported. This patch ensures such arguments are checked as well.
