Add support for user-defined assignment, as well as compound assignment and increment, following the design direction in pending proposal #2511. Some of this isn't fully testable yet: because explorer doesn't properly support `impl` specialization, the blanket `impl`s in the prelude prevent types from customizing assignment.
