	* config/frv/frv-modes.def: Fix comment typos.
	(CC_NZ): Define new mode.
	* config/frv/frv-protos.h (frv_select_cc_mode): Declare.
	(condexec_intop_cmp_operator): Delete.
	* config/frv/frv.c (comparison_string): New function.
	(frv_print_operand): Use it to handle 'c' and 'C'.
	(relational_operator): Redefine in terms of integer_relational_operator
	and float_relational_operator.
	(signed_relational_operator, unsigned_relational_operator): Delete.
	(integer_relational_operator): New predicate, combining the above.
	Check the mode of the first operand but leave frv.md to check the rest.
	(float_relational_operator): Just check the mode of the first operand
	and leave frv.md to check the rest.
	(intop_compare_operator): Assume the result is compared with zero
	in mode CC_NZmode.  Allow PLUS and MINUS.  Leave frv.md to check
	the operand predicates.
	(condexec_intop_cmp_operator): Delete.
	(frv_ifcvt_modify_tests, frv_ifcvt_modify_multiple_tests)
	(frv_hard_regno_mode_ok): Handle CC_NZmode.
	(frv_select_cc_mode): New function.
	* config/frv/frv.h (SELECT_CC_MODE): Use frv_select_cc_mode.
	(REVERSIBLE_CC_MODE): Include CC_NZmode.
	(PREDICATE_CODES): Replace entries for signed_relational_operand and
	unsigned_relational_operator with one for integer_relational_operator.
	Delete entry for condexec_intop_cmp_operator.

	(*combo_intop_compare2, *combo_intop_compare4): Delete.
	(*combo_intop_compare1): Change mode to CC_NZ.
	(*combo_intop_compare2): Likewise.  Renamed from *combo_intop_compare3.
