       cc1: Avoid out of bound access
       
       The function emitstrings() goes over all the elements of the initializer
       to dump any string involved in the initializer, and it uses the nary value
       from the type of the initializer. But this is wrong because in unions we
       have as many files as declared in the type, but we van have only one
       item in the initializer, and this was causing an out of order access.
