fix bugs exposed in #677. to_int(x) has the semantics that to_int(x) <= x, and to_int(x) is the largest integer satisfying this inequality. The encoding in purify_arith had it the other way x <= to_int(x) contrary to how to_int(x) is handled elsewhere. Another bug in theory_arith for mixed-integer linear case was also exposed. Fractional bounds on expressions of the form to_int(x), and more generally on integer rows were not rounded prior to internalization
