This commit adds the following integer comparison involving min/max and select rules that lift bitwise and arithmetic not. ``` smin(x, y) > smax(x, y) --> false umin(x, y) > umax(x, y) --> false smin(x, y) <= smax(x, y) --> true umin(x, y) <= umax(x, y) --> true smin(x, y) == smax(x, y) --> x == y smin(x, y) != smax(x, y) --> x != y select(c, ~x, ~y) --> ~select(c, x, y) select(c, -x, -y) --> -select(c, x, y) ``` Co-authored-by: Zijian Yi <zijianyi66@gmail.com>

There was a problem hiding this comment.
These sound right, and more importantly verifier passes them and adds new queries, so LGTM!
