* config/c4x/c4x.c (call_address_operand, symbolic_address_operand):

 	Rename from call_operand and symbolic_operand respectively.  All
	callers changed.
	* config/c4x/c4x.md (call_address_operand, symbolic_address_operand):
	Likewise.
	* config/c4x/c4x.h (call_address_operand, symbolic_address_operand):
	Likewise.
	(PREDICATE_CODES): Allow CONST, LABEL_REF for call_address_operand.
