Add substr, contains and equality rewrites
This commit adds three new rewrites:
- `(str.contains (str.replace x y z) w) ---> (str.contains (str.replace
x y "") w)` if `(str.contains z w) ---> false` and `(str.len w) = 1`
- `(= (str.replace x y z) z) ---> (or (= x y) (= x z))` if `(str.len y)
= (str.len z)`
- `(str.substr s x y) --> ""` if `0 < y |= x >= str.len(s)`
