[PATCH 18/29] [arm] Cleanup dead code - old support for DImode comparisons

[Richard Earnshaw]

Now that all the major patterns for DImode have been converted to
early expansion, we can safely clean up some dead code for the old way
of handling DImode.

	* config/arm/arm-modes.def (CC_NCV, CC_CZ): Delete CC modes.
	* config/arm/arm.c (arm_select_cc_mode): Remove old selection code
	for DImode operands.
	(arm_gen_dicompare_reg): Remove unreachable expansion code.
	(maybe_get_arm_condition_code): Remove support for CC_CZmode and
	CC_NCVmode.
	* config/arm/arm.md (arm_cmpdi_insn): Delete.
	(arm_cmpdi_unsigned): Delete.
