cc622608db new lints around #[must_use] fns 
`must_use_unit` lints unit-returning functions with a `#[must_use]`
attribute, suggesting to remove it.

`double_must_use` lints functions with a plain `#[must_use]`
attribute, but which return a type which is already `#[must_use]`,
so the attribute has no benefit.

`must_use_candidate` is a pedantic lint that lints functions and
methods that return some non-unit type that is not already
`#[must_use]` and suggests to add the annotation.

2a13e83f2b Update all the code to pass the updated use_self lint. 
One struct required a temporary `#[allow(dead_code)]` annotation due to
a bug in the Rust compiler: https://github.com/rust-lang/rust/issues/63151.

Fix ICE in decimal_literal_representation lint 
Handling the integer parsing properly instead of just unwrapping.

Note that the test is not catching the ICE because plain UI tests
[currently hide ICEs][compiletest_issue]. Once that issue is fixed, this
test would fail properly again.

3f62fc3a7e Remove crate:: prefixes from crate paths 
This is somewhat misleading, as those are actually external crates,
and don't need a crate:: prefix.

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.

7e417d4cbd Merge #3353 
3353: float support added for mistyped_literal_suffixes lint r=mikerite a=Maxgy

I implemented the mistyped_literal_suffixes lint for float literals.

```
#![allow(unused_variables)]

fn main() {
    let x = 1E2_32;
    let x = 75.22_64;
}
```
Given the above, the additional check suggests the variables to be written as `let x = 1E2_f32` and `let x = 75.22_f64`.

Fixes #3167
