(Where block return is the thing that happens with semicolon-less last expressions.) Both guarantee that the returned value is no longer live after the return, so there doesn't seem to be a reason to copy.

Lint enum-to-int casts with `cast_possible_truncation`

fixes: rust-lang#542

~~This will not lint casting a specific variant to an integer. That really should be a new lint as it's definitely a truncation (other than `isize`/`usize` values).~~

changelog: Lint enum-to-int casts with `cast_possible_truncation`
changelog: New lint `cast_enum_truncation`
