Suggest `==` to wrong assign expr
Given the following code:
```rust
fn main() {
let x = 3;
let y = 3;
if x == x && y = y {
println!("{}", x);
}
}
```
Current output is:
```
error[E0308]: mismatched types
--> src/main.rs:4:18
|
4 | if x == x && y = y {
| ^ expected `bool`, found integer
error[E0308]: mismatched types
--> src/main.rs:4:8
|
4 | if x == x && y = y {
| ^^^^^^^^^^^^^^^ expected `bool`, found `()`
```
This adds a suggestion:
```diff
error[E0308]: mismatched types
--> src/main.rs:6:18
|
6 | if x == x && y = y {
| ^ expected `bool`, found integer
error[E0308]: mismatched types
--> src/main.rs:6:8
|
6 | if x == x && y = y {
| ^^^^^^^^^^^^^^^ expected `bool`, found `()`
|
+ help: you might have meant to compare for equality
+ |
+ 6 | if x == x && y == y {
+ | +
```
And this fixes a part of #97469
