h8300.c (h8300_eightbit_constant_address_p): New.

	* config/h8300/h8300.c (h8300_eightbit_constant_address_p): New.
	(h8300_tiny_constant_address_p): Likewise.
	* config/h8300/h8300.h (EIGHTBIT_CONSTANT_ADDRESS_P): Use
	h8300_eightbit_constant_address_p.
	(TINY_CONSTANT_ADDRESS_P): Use h8300_tiny_constant_address_p.
	* config/h8300/h8300-protos.h: Add the prototypes for the two
	new functions.
