or_patterns: implement :pat edition-specific behavior

cc #54883 `@joshtriplett`

This PR implements the edition-specific behavior of `:pat` wrt or-patterns, as determined by the crater runs and T-lang consensus in https://github.com/rust-lang/rust/issues/54883#issuecomment-745509090.

I believe this can unblock stabilization of or_patterns.
