wrong_self_convention: fix lint in case of `to_*_mut` method

fixes #6758
changelog: wrong_self_convention: fix lint in case of `to_*_mut` method. When a method starts with `to_` and ends with `_mut`, clippy expects a `&mut self` parameter, otherwise `&self`.

Any feedback is welcome. I was also thinking if shouldn't we treat `to_` the same way as `as_`. Namely to accept `self` taken:  `&self` or `&mut self`.

7be3a32f25 Auto merge of #6843 - Jarcho:match_on_same_arms_macro, r=Manishearth
Compare empty blocks for equality based on tokens

fixes: #1390

This only considers empty blocks for now, though we should also catch something like this:

```rust
match 0 {
    0 => {
        do_something();
        trace!(0);
        0
    }
    1 => {
        do_something();
        trace!(1);
        1
    }
    x => x,
}
```

As far as I can tell there aren't any negative effects on other lints. These blocks only happen to be the same for a given compilation, not all compilations.

changelog: Fix `match_on_same_arms` and others. Only consider empty blocks equal if the tokens contained are the same.

Fix false positive for unit_arg lint

Fixes #6447

To avoid false positives don't complain about unit args when they come from a path expression, e.g. a local variable.

**Note:** This is my first contribution to Clippy, so I might have messed up somewhere. Any feedback is welcome and I'm happy to work out any kinks.

2f0e9f7d3a or_fun_call: fix suggestion for or_insert(vec![])
Applies for `std::collections::hash_map::Entry` and `std::collections::btree_map::Entry`

Example:
Previously, for the following code:
`let _ = hash_map.entry("test".to_owned()).or_insert(vec![]);`
clippy would suggest to use:
`or_insert_with(vec![])`, which causes a compiler error (E0277).

Now clippy suggests:
`or_insert_with(Vec::new)`
