I was becoming irritated by garbage like
(note 188 212 217 NOTE_INSN_DELETED -1347440721)
where that negative number is left over from the insn.
It seemed easier to just not print the field instead
of track down all the places that might ocurr.
r~
* print-rtl.c (print_rtx) [i]: Don't print field five on
NOTEs other than NOTE_INSN_DELETED_LABEL.
