Inline constructors vs. Void (continued)

This code kills the analyzer with a stack overflow:

```haxe
function main() {
[var tmp];
}
```

While I definitely want to fix that in the analyzer too, the code that comes out of the inline constructor processing has a problem too:

```
[Function:() -> Void]
[Block:Array]
[Var inlarr_0<6843>(VAssigned):Void]
[Binop:Void]
[Local inlarr_0(6843):Void:Void]
=
[Block:Void]
```

There shouldn't be an empty `TBlock` in a value place.
