Issue: For compiler generated trees the MemberInfos always in sync. But for manually generated trees, if derived type parameter is used then the MemberInfo.ReflectedType is different. Which throws off ReplacingExpressionVisitor when comparing MemberInfo.
Fix: Use helper method IsSameAs which compare memberInfos which refer to same member access in given hierarchy
