`unreachable` coverage

[wyfo]

As the name suggests unreachable (and hint::unreachable_unchecked) should never be reached. Does it make sense to automatically exclude unreachable branches from coverage? Is it even possible?

There is an open upstream PR to implement this: rust-lang/rust#120013
See also rust-lang/rust#80549

My bad, I should have looked there first.
I imagine that you prefer having the problem solved on Rust side rather than hacking llvm-cov result, so I will close the issue.
