    Original change's description:
    > Sync ProcessorEntity: Upgrade remaining DCHECKs
    >
    > This CL upgrades most of the remaining DCHECKs in ProcessorEntity to
    > proper CHECKs, mostly with base::NotFatalUntil::M141.
    > A few that are obviously-valid don't have NotFatalUntil, and one that
    > is questionable is just removed.
    >
    > Also includes some minor other cleanups, like inlining a one-line
    > helper method with a single call site.
