> Project: IMPALA

>
> Impala's ExprRewriteRules may not be completely applied for complex
> expressions. Some implementations of ExprRewriteRule don't analyze new Expr
> they produce, which can lead to other rewrite rules ignoring those Expr.
> reAnalyze covers some of this by doing a 2nd analysis phase, but that only
> works for two layers.
> We should analyze any new Expr produced by an ExprRewriteRule.
