> * {{IF}} is not part of the sql standard; however given its special form its
> simpler - and currently in Hive it also has vectorized support
> * people writing standard sql may write: {{CASE WHEN member=1 THEN attr+1
> else attr+2 END}} which is essentially an if.
> The idea is to rewrite IFs to CASEs for the cbo; and recognize simple
> "CASE"-s as IFs to get vectorization on them if possible
