0ab75c37b6 Auto merge of #5977 - xvschneider:AddLintPanicInResult, r=matthiaskrgr 
Add lint panic in result

### Change
Adding a new "restriction" lint that will emit a warning when using "panic", "unimplemented" or "unreachable" in a function of type option/result.

### Motivation
Some codebases must avoid crashes at all costs, and hence functions of type option/result must return an error instead of crashing.

### Test plan
Running:
TESTNAME=panic_in_result cargo uitest ---

f23670ed68 Adjust Clippy for CONST_ITEM_MUTATION lint 
We no longer lint assignments to const item fields in the
`temporary_assignment` lint, since this is now covered by the
`CONST_ITEM_MUTATION` lint.

Additionally, we `#![allow(const_item_mutation)]` in the
`borrow_interior_mutable_const.rs` test. Clippy UI tests are run with
`-D warnings`, which seems to cause builtin lints to prevent Clippy
lints from running.

default_trait_access: Fix wrong suggestion

https://github.com/rust-lang/rust-clippy/issues/5975#issuecomment-683751131
> I think the underlying problem is clippy suggests code with complete parameters, not clippy triggers this lint even for complex types. AFAIK, If code compiles with `Default::default`, it doesn't need to specify any parameters, as type inference is working. (So, in this case, `default_trait_access` should suggest `RefCell::default`.)

Corrects the float_equality_without_abs lint

Fixes an issue in the `float_equality_without_abs` lint. The lint suggestion was configured in a way that it lints the whole error and not just the subtraction part. In the current configuration the lint would suggest to change the expression in a wrong way, e.g.
```rust
let _ = (a - b) < f32::EPSILON; // before
let _ = (a - b).abs(); // after
```
This was dicovered by @flip1995. (See discussion of PR #5952).

Also the suggestion is now formatted via `utils::sugg`.

Don't lint if it has always inline attribute

Don't trigger the lint `trivially_copy_pass_by_ref` if it has `#[inline(always)]` attribute.

Note: I am not particularly familiar with `inline` impacts, so I implemented this the way that if only `#[inline]` attribute is here (without `always`), the lint will still trigger. Also, it will still trigger if it has `#[inline(never)]`.
Just tell me if it sounds too much conservative.

Warn about assignments where left-hand side place expression is the same
as right-hand side value expression. For example, warn about assignment in:

```rust
pub struct Event {
    id: usize,
    x: i32,
    y: i32,
}

pub fn copy_position(a: &mut Event, b: &Event) {
    a.x = b.x;
    a.y = a.y;
}

Add the other overloadable operations to suspicious_arithmetic_impl

In #2268 I idly mused that the other user-overloadable operations could be added to this lint. Knowing that the lint was arguably incomplete was gnawing at the back of my mind, so I figured that I might as well make this PR, particularly given the change needed was so small.

changelog: Start warning on suspicious implementations of the `BitAnd`, `BitOr`, `BitXor`, `Rem`, `Shl`, and `Shr` traits.

9e73d33680 Rollup merge of #75098 - Ryan1729:clippy-pointer-cast-lint-experiment, r=oli-obk 
Clippy pointer cast lint experiment

This PR is an experiment about exposing more parts of `rustc_typeck` for use in `clippy`. In particular, the code that checks where a cast is valid or not was exposed, which necessitated exposing [`FnCtxt`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_typeck/check/struct.FnCtxt.html), and figuring out how to create an instance of that type inside `clippy`.

This was prompted by [this clippy issue](https://github.com/rust-lang/rust-clippy/issues/2064).
