predicates.md (rx_zs_comparison_operator): Remove lt and ge.
* config/rx/predicates.md (rx_zs_comparison_operator): Remove
lt and ge.
* config/rx/rx.md (abssi2_flags): Use CC_ZSmode rather than
CC_ZSOmode.
* config/rx/rx.c (rx_print_operand): Use "lt" and "ge" suffixes
instead of "n" and "pz".
(flags_from_code): LT and GE tests need CC_FLAG_O as well as
CC_FLAG_S.
