Validate ispell dictionaries more carefully.
Using incorrect, or just mismatched, dictionary and affix files
could result in a crash, due to failure to cross-check offsets
obtained from the file. Add necessary validation, as well as
some Asserts for future-proofing.
Per bug #16050 from Alexander Lakhin. Back-patch to 9.6 where the
problem was introduced.
Arthur Zakirov, per initial investigation by Tomas Vondra
