m32c.h (CLASS_MAX_NREGS): Remove macro. 

* config/m32c/m32c.h (CLASS_MAX_NREGS): Remove macro.
	* config/m32c/m32c-protos.h (m32c_class_max_nregs): Remove.
	* config/m32c/m32c.c (m32c_class_max_nregs): Make static. Change
	regclass argument type to reg_class_t. Change 'max' and 'v' vars
	and return types to unsigned char. Use reg_class_contents instead
	of class_contents.
	(TARGET_CLASS_MAX_NREGS): Define.
