  1. Add rewrite for array selects of chain of stores of a same value 

    Example:
```smt
(declare-fun mem () (Array (_ BitVec 4) (_ BitVec 4)))
(declare-const x (_ BitVec 4))
(declare-const y (_ BitVec 4))
; simplifies to #x1
(simplify (select (store (store (store mem #x1 #x1) y #x1) x #x1) #x1))
```
