Research direction

Start with the linked Treeherder job log and trace bindgen's handling of mozilla::HashSet and mozilla::HashMap for Linux32. Identify where the reported non-primitive cast from [u32; 2] to u64 is produced. Done means the affected bindings generate successfully without this error.
