Use up to 8 affixes in Hunspell spellcheck suggestions

Chrome has been suggesting "Othello" for "hellllo" and "identically" for
"accidently" because it has been ignoring dictionary entries with more than one
affix. This CL changes Chrome behavior to take these entries into consideration
and use up to 8 affixes in suggestions.
