Normalize check constraints even more radically

This is the only way I could get this test pass on informix, basically I strip every whitespace.
The sql text as recorded in informix is:
```
((a > 1 ) AND (a < 5 ) )
((a = 1 ) OR ((a > 2 ) AND (a <5 ) ) )
```
Yes, this is absolutely bonkers, but that is what I get :(
