02a66c425e add option to bypass quick returns in integer theory integration in theory_str 
this might not actually be that useful, if the problem is, as I suspect it to be,
that values we get from the integer theory need not correspond with
assertions in the core (that can get popped off the stack, etc.)

3989d238c0 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
