	* sh.c (print_operand, case 'N'): Allow zero vector.
	(arith_reg_or_0_operand): Likewise.
	(zero_vec_operand): Check for CONST_VECTOR, not PARALLEL.
	* sh.h (CONST_COSTS): 0 has 0 cost.  Check OUTER_CODE for
	IOR, XOR, PLUS and SET and take their respective constant
	ranges into account.
	(PREDICATE_CODES, arith_reg_or_0_operand): Can be CONST_VECTOR.
	* sh.md (subdi3, subdi3_media): Allow zero operand.
	(movv8qi_i+3): Only vector that is not split is the zero vector.
	Fix operand 3 to simplify_subreg.
	(movv2si_i): Split alternative 1.
	(mshfhi_l_di_rev+1): New splitter.
