Generate safe stable code for derives on empty enums
Generate `match *self {}` instead of `unsafe { core::intrinsics::unreachable() }`.

This is:

    1. safe
    2. stable

for the benefit of everyone looking at these derived impls through `cargo expand`.

Both expansions compile to the same code at all optimization levels (including `0`).
