Tactic Documentation:

## Tactic propagate-bv-bounds

### Short Description

Contextual bounds simplification tactic.

### Example

```z3
(declare-const x (_ BitVec 32))
(declare-const y (_ BitVec 32))
(declare-const z (_ BitVec 32))
(assert (bvule (_ bv4 32) x))
(assert (bvule x (_ bv24 32)))
(assert (or (bvule x (_ bv100 32)) (bvule (_ bv32 32) x)))
(apply propagate-bv-bounds)
```

### Notes

* assumes that bit-vector inequalities have been simplified to use bvule/bvsle
