-Note(Lokathor): We've switched all of the `unwrap` to `match` because there is
-apparently a bug: https://github.com/rust-lang/rust/issues/68667
-and it doesn't seem to show up in simple godbolt examples but has been reported
-as having an impact when there's a cast mixed in with other more complicated
-code around it. Rustc/LLVM ends up missing that the `Err` can't ever happen for
-particular type combinations, and then it doesn't fully eliminated the panic
-possibility code branch.
