And add assert_eq, assert_ne, assert_matches support

Input:

```rust
pub fn $0foo(x: bool) {
    debug_assert!(x);
}
```

Old:

```rust
/// .
///
/// # Panics
///
/// Panics if .
pub fn foo(x: bool) {
    debug_assert!(x);
}
```

This PR fixes:

```rust
/// .
pub fn foo(x: bool) {
    debug_assert!(x);
}
```
