class ResolveZipJoins extends Phase
Rewrite zip joins into a form suitable for SQL using inner joins and RowNumber columns.
We rely on having a Bind around every Join and both of its generators, which should have been
generated by Phase.forceOuterBinds. The inner Binds need to select Pure(StructNode(...))
which should be the outcome of Phase.flattenProjections.
