* config/alpha/alpha.c (alpha_legitimize_reload_address)
	(alpha_preferred_reload_class, alpha_legitimate_constant_p): Use
	CONST_INT_P, CONST_SCALAR_INT_P and CONST_DOUBLE_P predicates.
	(alpha_split_reload_pair) <case CONST_INT, case CONST_WIDE_INT>:
	Use CASE_CONST_SCALAR_INT.
	(print_operand) <case 'M'>: Use mode_width_operand to check the
	value of the constant.
	* config/alpha/alpha.md (movti): Use CONST_SCALAR_INT_P predicate.
	* config/alpha/predicates.md (input_operand): Use general_operand
	instead of match_code as operand check.
	(symbolic_operand): Use match_code with subexpression digits.
	* config/alpha/constraints.md (Q): Ditto.
