pru: Drop usage of ATTRIBUTE_UNUSED

Remove usage of ATTRIBUTE_UNUSED.  Instead remove the argument's name,
which in C++ means that the argument would not be used.

gcc/ChangeLog:

	* config/pru/pru-passes.cc: Drop ATTRIBUTE_UNUSED and remove
	argument's name.
	* config/pru/pru-pragma.cc (pru_pragma_ctable_entry): Ditto.
	* config/pru/pru.cc (pru_function_profiler): Ditto.
	(pru_can_eliminate): Ditto.
	(pru_rtx_costs): Ditto.
	(pru_insert_attributes): Ditto.
	(pru_function_value): Ditto.
	(pru_libcall_value): Ditto.
	(pru_return_in_memory): Ditto.
	(pru_builtin_decl): Ditto.
	(pru_expand_builtin): Ditto.
