Fix bogus affix-merging code.

NISortAffixes() compared successive compound affixes incorrectly,
thus possibly failing to merge identical affixes, or (less likely)
merging ones that shouldn't be merged.  The user-visible effects
of this are unclear, to me anyway.

Per bug #15150 from Alexander Lakhin.  It's been broken for a long time,
so back-patch to all supported branches.
