h8300.c (get_shift_alg): Remove an argument cpu. 

2001-01-09  Kazu Hirata  <kazu@hxi.com>

	* config/h8300/h8300.c (get_shift_alg): Remove an argument cpu.
	Change an argument mode of machine_mode to shift_mode of
	shift_mode.  Remove an extra error check.
	(emit_a_shift): Adopt to the new calling prototype of
	get_shift_alg.
