    [PR94044] Fix ICE with sizeof<argumentpack>

    Thanks to Jim for figuring out how to reproduce the problem, I was
    able to apply pr94044-jig.diff to poorly hash the specialization
    table. (That places all the specializations of a particular template
    in the same bucket, forcing us to compare the arguments.)

    The testcase creates sizeof_exprs containing argument packs, and we
    can no longer use same_type_p on those.
