Fix asymmetry in QVariant::cmp when A converts to B but not the opposite
This would result in (a == b) != (b == a). The == operation should be commutative as much as possible. Now, there's still an asymmetry in that b is forced to a type and the conversion may fail. QVariant should have an idea of what conversions are "promotion" and which ones are "demotion" (subject to loss of data and/or can fail), so it can do the promotion first Task-number: QTBUG-42254 Change-Id: I9fa4496bbbf0f8719ff8456cc24247290beac608 Reviewed-by: Jędrzej Nowacki <>
