I'd rather not, as this way it's much simple to change the 'invalid'
indicator if need be. Also, the special case handling isn't only about
blank fields, but also about missing trailing ones - if you want that
removed, too, it'd mean adding much more useless stuff to registers
not validly subject of .cfi_* directives.
