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`).
