a22578d3 - ConstraintElim: teach fact-transfer about samesign (#115893)

ConstraintElim: teach fact-transfer about samesign (#115893) When the samesign flag is present on an icmp, we can transfer all the facts on the unsigned system to the signed system, and vice-versa: we do this by specializing transferToOtherSystem when samesign is present.
