Thanks.

I'm not yet sure which part(s) of the changeset directly shut up the
"-Walloc-size-larger-than=N" warnings.  Is that the part that adds the
calls to 'assume'?  If so, we already call eassume in many places; it
won't be a problem to add a few more, and fix the warnings on the
emacs-27 branch.

And what about a similar warning I reported in bug#39857?
