Fix auto-corrected typos: ... accessable -> accessible accidently -> accidentally accomodate -> accommodate adress -> address afair -> affair agains -> against agressively -> aggressively annuled -> annulled arbitary -> arbitrary arround -> around auxillary -> auxiliary availablity -> availability clasic -> classic comming -> coming controled -> controlled controling -> controlling destory -> destroy existance -> existence explictly -> explicitly faciliate -> facilitate fouth -> fourth fullfilled -> fulfilled guarentee -> guarantee hinderance -> hindrance independant -> independent inital -> initial loosing -> losing occurance -> occurrence occured -> occurred occuring -> occurring omited -> omitted oportunity -> opportunity parallely -> parallelly permissable -> permissible postive -> positive powerfull -> powerful preceed -> precede preceeding -> preceding preceeds -> precedes primative -> primitive probaly -> probably programable -> programmable propogate -> propagate propper -> proper recieve -> receive reconized -> recognized refered -> referred refering -> referring relevent -> relevant responisble -> responsible retreive -> retrieve safty -> safety specifiying -> specifying spontanous -> spontaneous sqaure -> square successfull -> successful supress -> suppress sytem -> system thru -> through transfered -> transferred trigered -> triggered unfortunatly -> unfortunately upto -> up to usefull -> useful wierd -> weird writen -> written doesnt -> doesn't isnt -> isn't ... Manually undid the "andd -> and" transformation in sim/testsuite/cr16/andd.cgs and sim/cr16/simops.c. Tested by rebuilding on x86_64-linux. Approved-By: Tom Tromey <tom@tromey.com>
