MAX_FIXED_MODE_SIZE vs. attribute(mode) vs. ABIs

    MAX_FIXED_MODE_SIZE should be deprecated.  About the only thing that
    it should be used for right now is mode assigment for aggregates.

Was it *ever* used for more than that?  The furthest back I have online
is 2.8.1 and it was only used in that one place there.

But if it's deprecated, what would be used instead for that determination?
