Suggest == to wrong assign expr

[TaKO8Ki]

Given the following code:

fnmain(){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:

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
