Reverting the idea that RefinedThis types take levels.
In the end, this did not buy us anything. What matters is that
- we can reliably identify RefinedThis types pointing to a given
refinement type. Making sure that the `binder` field of q RefinedThis
type in a refinedInfo is always the containing refined type is good
enough for that.
- we take care to rebind RefinedThis types in isSubType. This was leaky before,
is handled now better in the new isSubType.
So, in the end, adding a level was a needless complication. Also, as a next step
we should be able to identify skolem types and RefinedThis types.
