## 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
