Description
Depends on #880.
We should be conservative and only implement this when the reason we cannot derive is because we're hitting the array length derive limit and similar easy cases. We can't know all the corner cases for types we have no knowledge of, and we shouldn't try.

Research direction
Start by reading dependent issue #880 and then trace the existing Eq derivation path in bindgen. The work is complete when Eq is implemented only for conservative, easy cases such as array-length derive limits, without attempting unsupported unknown-type cases.
