The reason for the extra fields in BARRIER and CODE_LABEL is to make it
possible for a BARRIER or CODE_LABEL to be turned into
INSN/JUMP_INSN/CALL_INSN. So you'd need to verify it isn't needed anywhere.
Note, your reordering of CODE_LABEL fields doesn't change anything on the
allocated size, even tail 0 format fields are allocated.
