[AUTO-GENERATED] Migrate ui tests from // to //@ directives 2024-02-16 20:02:50 +00:00
AngelicosPhosphoros 7c263adb2a Add support for cfg(overflow_checks) 
This PR adds support for detecting if overflow checks are enabled in similar fashion as debug_assertions are detected.
Possible use-case of this, for example, if we want to use checked integer casts in builds with overflow checks, e.g.

```rust
pub fn cast(val: usize)->u16 {
    if cfg!(overflow_checks) {
        val.try_into().unwrap()
    }
    else{
        vas as _
    }
}
```

Resolves #91130.
Tracking issue: #111466.
