Mads Ager 05ff2b1292 [JVM_IR] Extend when to switch translation to deal with nested ors.
FIR translates:

```
when (x) {
  1, 2, 3 -> action
  else -> other_action
}
```

to an IR structure with nested ors:

```
if ((x == 1 || x == 2) || (x == 3)) action
else other_action
```

This change allows that to turn into switch instructions in the
JVM backend.
