ConstantOverflow has unhelpful suggestion for divide-by-zero

With this source:
```
public class Divide {
public void divide() {
var unused = 1/0;
}
}
```
errorprone complains with
```
Divide.java:3: error: [ConstantOverflow] Compile-time constant expression overflows
var unused = 1/0;
^
(see https://errorprone.info/bugpattern/ConstantOverflow)
Did you mean 'var unused = 1L/0;'?
```
But `long` isn't capable of holding an undefined number either.
