Original change's description:
> [dart2js] Patch experimental inferrer (with linearized algorithm) into main inferrer.
>
> After this change for a large program we see:
> - 20% reduction in runtime (254s -> 202s)
> - 2% decrease in memory usage (7671.029MB -> 7524.901MB)
> - Code size decrease of <1% (214,788,150 bytes -> 214,757,445 bytes).
> - The k-limit of 6 refines imposed on the global inference algorithm is no longer hit for converging types. All but 15 types converge, down from 777 types that were hitting the k-limit before. This means we are likely generating better types/code for all 762 of those types.
> - More resilience to dynamic calls with lots of potential targets.
