Attached patch removes in arm_function_arg() a superfluous test on one
of its parameters as that test is already done at the beginning of the
routine and the parameter doesn't change during the function.

	* config/arm/arm.c (arm_function_arg): Remove superfluous test.

Please commit after positive review.

John.
