Hi Huan, as I understand it, this PR is trying to reduce GC pressure by reducing the declaration of large data structures, such as spammers. Logically this is very reasonable.

I have a small concern because spammers seems like not a thread-safe priority queue. But it seems the txpool will be locked by https://github.com/mask-pp/go-ethereum/blob/up_tps/core/tx_pool.go#L1172?  If so, looks good to me.

The used place of pool.spammers is in truncatePending func, and truncatePending locked in the pool.mu.lock() pool.mu.Unlock() area. So it's safe.
