Equality of those values is crucial for intersecting data-flow info coming from expressions like: 'this.x != null || other.x != null'. Using 'ValueDescriptor' for equality is obviously wrong, because then 'this.x' and 'other.x' will be treated as equal, leading to unsound smartcasts. This commit adds proper overload of 'equals' to 'ESDataFlowValue' that will compare them based on underlying 'DataFlowValue' (which already distinguish those values) ^KT-27260 Fixed
