From the pull request description

Platforms no longer treat `if` specially. Instead, platforms can define operations that implement the `(if c t f)` specification (or not) and can define as many of these as they want. In *many* places in Herbie we no longer need to treat if statements specially. https://chatgpt.com/codex/tasks/task…
