This makes non-JS tracers execute all block txs on a single goroutine. In the previous implementation, we used to prepare every tx pre-state on one goroutine, and then run the transactions again with tracing enabled. Native tracers are usually faster, so it is faster overall to use their output as the pre-state for tracing the next transaction.
