Good catch, thanks!

IMO you could include as comments your explanations to existing cases where this optimization has not taken place (e.g. "This is not optimized into `bstrpick + slli` because the constant has multiple uses."), so future readers wouldn't have to do archaeology to see them. The code changes LGTM.
