* integrate.c (copy_insn_list): handle
NOTE_INSN_DELETED_LABEL, as if it were CODE_LABEL.
(copy_rtx_and_substitute): Likewise; behave to NOTE_INSN_DELETED_LABEL
identically as to CODE_LABEL.
* fold-const (fold): Convert A/B/C to A/(B*C) and
A/(B/C) to (A/B)*C
* except.c (connect_post_landing_pads): Delete the RESX insns.
