Blocks heavy in precompile calls (e.g. Aztec's proof settlement txs) spend most of their processing time on operations (ECMUL, pairings, KZG point evaluation, MODEXP) that the state prefetcher has already computed and thrown away. This PR adds a precompile result cache shared between the prefetcher and block processing (and the miner), following the JumpDestCache pattern. Note that cached precompiles are keyed by address and input, with entries partitioned by the active precompile set, so a fork that changes the behavior behind an address can never be served results from before it. --------- Co-authored-by: Gary Rong <garyrong0905@gmail.com>
