* Restricts permutative conversions for case-expressions to
non-booleans. This reduces the blow-up a bit.
Permutative conversions rewrite
```
case (case M | C1 -> A1 | C2 -> A2)
| D1 -> B1
| D2 -> B2
```
to
```
case M
| C1 -> case A1
| D1 -> B1
| D2 -> B2
| C2 -> case A2
| D1 -> B1
| D2 -> B2
```
It is necessary to perform them for non-boolean A1/A2 to obtain the
right kind of normal forms.
* Adds a test demonstrating the necessity of permutative conversions for
non-booleans.
