Finished a snap-sync (with blocks already present): https://geth-bench.ethdevops.io/d/Jpk-Be5Wk/dual-geth?orgId=1&from=1639661782210&to=1639685566480 . No obvious difference in charts, but it seems at least that it doesn't break anything. |

When doing some syncs, I noticed that in the heal phase, the db reads is going through the roof. This PR aims to bring that down a little bit, or at least reduce some allocation when that happens, by using
db.Haswherever possible.I'll do a benchmark later, also to verify that it doesn't break anything.
