The query analyzer coerces types as expected.
```
Projection: t1.v1
Inner Join: Using CAST(t1.v1 AS Utf8View) = t2.v1
SubqueryAlias: t1
TableScan: table1 projection=[v1]
SubqueryAlias: t2
TableScan: table1_stringview projection=[v1]
```
However, the `EliminateCrossJoin` optimizer rule converts this inner join
into a cross join for some reason, which seems to be incorrect.
