Commit cff6dda604cb0548bef5e5951dd1e74536110588 by richard
More accurately compute the ranges of possible values for +, -, *, &, %.

Continue to heuristically pick the wider of the two operands for
narrowing conversion warnings so that some_char + 1 isn't treated as
being wider than a char, but use the more accurate computation for
tautological comparison warnings.
