Document & implement the transmutation modeled by `BikeshedIntrinsicFrom`
Documents that BikeshedIntrinsicFrom models transmute-via-union, which is slightly more expressive than the transmute-via-cast implemented by transmute_copy. Additionally, we provide an implementation of transmute-via-union as a method on the BikeshedIntrinsicFrom trait with additional documentation on the boundary between trait invariants and caller obligations.
Whether or not transmute-via-union is the right kind of transmute to model remains up for discussion [1]. Regardless, it seems wise to document the present behavior.
