* core: use uint64 for total tx costs instead of big.Int * core: added local tx pool test case * core, crypto: various allocation savings regarding tx handling * Update core/tx_list.go * core: added tx.GasPriceIntCmp for comparison without allocation adds a method to remove unneeded allocation in comparison to tx.gasPrice * core: handle pools full of locals better * core/tests: benchmark for tx_list * core/txlist, txpool: save a reheap operation, avoid some bigint allocs Co-authored-by: Martin Holst Swende <martin@swende.se>
