Is this what we want to do for `[[assume]]`? We can do it this way: https://eel.is/c++draft/expr.const#5.8 but we can also do it better: https://eel.is/c++draft/expr.const#5.33

(We don't support assumptions yet, so I think the code is fine as-is, but I'm wondering if we want to add a FIXME here about `[[assume]]`. We should also see if any of our vendor statement attributes have UB we need to consider as well.)
