h8300-protos.h: Provide prototypes for h8300_legitimate_constant_p and h8300_legitimate_address_p.
* config/h8300/h8300-protos.h: Provide prototypes for
h8300_legitimate_constant_p and h8300_legitimate_address_p.
* config/h8300/h8300.c (h8300_legitimate_constant_p): New.

(h8300_legitimate_address_p): Likewise.
* config/h8300/h8300.h (LEGITIMATE_CONSTANT_P): Use
h8300_legitimate_constant_p.
(RTX_OK_FOR_BASE_P): Remove.
(GO_IF_LEGITIMATE_ADDRESS): Use h8300_legitimate_address_p.
