Sorry, I though the series had been approved at some point. In
general, adding final/override and removing redundant virtuals should be
considered trivial IMHO.
So just to be clear, OK for the trunk.

Thanks; I've pushed the remaining patches as r13-1305-g725793af78064f
through r13-1310-g26f77c4d19b827.
I had to do some minor refreshing of the patches against trunk to avoid
conflicts; I bootstrapped and regression-tested the result on x86_64-
pc-linux-gnu before pushing.
