I am not actively objecting to this patch, but I really don't like the overall direction here.  Having a threshold where our ability to optimize falls off a cliff just seems really undesirable.  As Hal pointed out, there are likely options for summarizing alias sets to allow quicker AA queries.  How much have we explored that design space?
