<pre>The following consteval if statements produce tautological warnings that don't
seem correct in all cases.
```
constexpr void f() {
if consteval {
if consteval { // Correct diagnostic
}
if !consteval { // Incorrect diagnostic
}
}
if !consteval {
if consteval { // Missing diagnostic
}
if !consteval { // Missing diagnostic
}
}
}
```
