change binding name of for loop lowering to appease clippy
With the latest change to for loop lowering, a `_next` binding was introduced. Unfortunately, this disturbs clippy's `used_underscore_binding` lint. This commit just renames the binding to `__next` so clippy will be happy. It should have no other effect.
