Disallow non-c-like but "fieldless" ADTs from being casted to integer... ... if they use arbitrary enum discriminant. Code like ```rust enum Enum { Foo = 1, Bar(), Baz{} } ``` seems to be unintentionally allowed so we couldn't disallow them now, but we could disallow them if arbitrary enum discriminant is used before 1.56 hits stable. 2021-09-24 15:58:25 -05:00			error[E0605]: non-primitive cast: `Kind2` as `u8`
