Currently, Int52 cases are just handled in double context. We should have a fast path for that since it is frequently called in kraken crypto.

First, I'll implement this optimization in runtime function, it should offer perf boost for all the tiers. After that, I'll investigate DFG / FTL Number#toString handling.
