- What about sign=true?
- Looks like this doesn't have tests, at least from the diff

- Sign
trueis+1, signnullis1, those dont change value of constant type - Tests are present in origin: #506 commit. Mostly I didnt add testcases to the old test as that one is MUCH worse. But I can add simple one to this separated PR.

The test I'm trying to write produces wrong results as those two are not merged yet:
- Proper aggregate function detection (even deeper in AST) #581
- Introduce DoctrineTypeDriverAwareDescriptor & DriverDetector #578
DQL from the test:
SELECT -o.intColumn as minusInt,
-o.floatColumn as minusFloat,
-COUNT(o.intColumn) as minusIntRange
FROM QueryResult\Entities\One o

Test added, it will fail once rebased on those PRs.
