ACCC: Handle A Class A0 Word
Used by the routines at StartPictureModeScreenIdle, CopyDisplayIfNeeded and RememberDisplayPage.
Skips class A0 tokens, saves the word pointer and this clause record, and carries on at the class B0 matcher (MatchWordAgainstEarlierClause). When the parser count at A019+01 is 02 it sets bit 6 of the clause record first.
