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
