## Tactic normalize-bounds
### Short Description
Replace $x$ with $x' + l$, when $l \leq x$
where $x'$ is a fresh variable.
Note that, after the transformation $0 \leq x'$.
### Example
```z3
(declare-const x Int)
(declare-const y Int)
(declare-const z Int)
(assert (<= 3 x))
(assert (<= (+ x y) z))
(apply normalize-bounds)
```
