Downgrade large_digit_groups to pedantic
I believe if the user already decided to put underscores in their
literal, Clippy should be willing to believe that they put a number of
underscores that they felt was readable.

Downgrade unsafe_vector_initialization to restriction
This lint looks for:

    let mut vec = Vec::with_capacity(len);
    vec.set_len(len);

The suggested replacement is `vec![0; len]`.

This is far too opinionated to be a deny-by-default lint because the performance
characteristics of the suggested replacement are totally different.

I am not convinced that this lint has value beyond what deny(unsafe_code) gives
you. Unsafe code is unsafe but please don't deny-by-default lint it if that's
the only reason.

e0ccc9d9af Add slow zero-filled vector initialization lint
Add lint to detect slow zero-filled vector initialization. It detects
when a vector is zero-filled with extended with `repeat(0).take(len)`
or `resize(len, 0)`.
This zero-fillings are usually slower than simply using `vec![0; len]`.

Downgrade needless_pass_by_value to allow by default
I noticed that I suppress this lint in many of my projects.

https://github.com/search?q=needless_pass_by_value+user%3Adtolnay&type=Code
https://github.com/search?q=needless_pass_by_value+user%3Aserde-rs&type=Code

Upon further inspection, this lint has a *long* history of false
positives (and several remaining).

Generally I feel that this lint is the definition of pedantic and should
not be linted by default.

    #[derive(Debug)]
    enum How {
        ThisWay,
        ThatWay,
    }

    // Are we really better off forcing the call sites to write f(&_)...?
    fn f(how: How) {
        println!("You want to do it {:?}", how);
    }

    fn main() {
        f(How::ThatWay);
    }

RIIR update lints: Add check mode (update_lints.py rewrite complete)
This finishes up the rewrite of `update_lints.py` in Rust. More
specifically, this

* adds the `--check` flag and handling to clippy_dev
* tracks file changes over the different calls to `replace_region_in_file`
* only writes changes to files if the `--check` flag is *not* used
* runs `./util/dev update_lints --check` on CI instead of the old script
* replaces usage of the `update_lints.py` script with an error

`./util/dev update_lints` behaves 99% the same as the python script.
The only difference that I'm aware of is an ordering change to
`clippy_lints/src/lib.rs` because underscores seem to be sorted
differently in Rust and in Python.

3388: RIIR update lints: Generate deprecated lints r=phansch a=phansch

The update script now also generates the 'register_removed' section in
`clippy_lints/src/lib.rs`.

Also, instead of using `let mut store ...`, I added a new identifier
line so that the replacement will continue to work in case `let mut
store ...` ever changes.

cc87dc7539 Move some range lints to complexity
Recategorize `range_plus_one` and `range_minus_one` to `complexity`.
This moves `range_plus_one` out of the nursery as the inclusive range
syntax is now stable. Both are moved to `complexity` as it is more
consistent with other lints such as `int_plus_one`.

This commit represents an attempt to address changes requested in the process of reviewing PR #2790.
The changes reflected in this commit are as follows:

- Revised `IndexingSlicingPass` struct name to IndexingSlicing for consistency with the rest of the code base.
- Revised match arm condition to use `(..)` shorthand in favor of `(_, _, _)`.
- Restored a couple telling variable names.
- Calls to `cx.span_lint` were revised to use `utils::span_help_and_lint`.
- Took a stab at refactoring some generalizable calls to `utils::span_help_and_lint` to minimize duplicate code.
- Revised INDEXING_SLICING declaration to pedantic rather than restriction.
- Added `&x[0..].get(..3)` to the test cases.

Rename instances of array_indexing
This commit renames instances of `array_indexing` to `indexing_slicing` and moves the `indexing_slicing` lint to the `clippy_pedantic` group. The justification for this commit's changes are detailed in the previous commit's message.

Extend indexing_slicing lint
Hey there clippy team! I've made some assumptions in this PR and I'm not at all certain they'll look like the right approach to you. I'm looking forward to any feedback or revision requests you have, thanks!

    Prior to this commit the `indexing_slicing` lint was limited to indexing/slicing operations on arrays. This meant that the scope of a really useful lint didn't include vectors. In order to include vectors in the `indexing_slicing` lint a few steps were taken.

    The `array_indexing.rs` source file in `clippy_lints` was renamed to `indexing_slicing.rs` to more accurately reflect the lint's new scope. The `OUT_OF_BOUNDS_INDEXING` lint persists through these changes so if we can know that a constant index or slice on an array is in bounds no lint is triggered.

    The `array_indexing` tests in the `tests/ui` directory were also extended and moved to `indexing_slicing.rs` and `indexing_slicing.stderr`.

    The `indexing_slicing` lint was moved to the `clippy_pedantic` lint group.

    A specific "Consider using" string was added to each of the `indexing_slicing` lint reports.

    At least one of the test scenarios might look peculiar and I'll leave it up to y'all to decide if it's palatable. It's the result of indexing the array `x` after `let x = [1, 2, 3, 4];`

    ```
    error: slicing may panic. Consider using `.get(..n)`or `.get_mut(..n)`instead
      --> $DIR/indexing_slicing.rs:23:6
       |
    23 |     &x[0..][..3];
       |      ^^^^^^^^^^^
    ```

    The error string reports only on the second half's range-to, because the range-from is in bounds!

    Again, thanks for taking a look.

    Closes #2536

This checks for things like

    if x.is_some() {
        x.unwrap()
    }

which should be written using `if let` or `match` instead.

In the process I moved some logic to determine which variables are
mutated in an expression to utils/usage.rs.

5f3c340bfb Lint for trait methods without bodies
As discussed in rust-lang/rust#47475 the #[inline] attribute is
currently allowed on trait methods without bodies (i.e. without a
default implementation). This is misleading as it could be interpreted
as affecting the implementations of the trait method. Add a lint for any
use of #[inline] on a trait method without a body.

Fixes rust-lang/rust#47475
