3677 C_MAYBE_CONST_EXPR, if they have integer operands. Use
3678 c_objc_common_truthvalue_conversion not
3679 c_common_truthvalue_conversion.
3680 (c_objc_common_truthvalue_conversion): Build NE_EXPR directly and
3681 call note_integer_operands for arguments with integer operands
3682 that are not integer constants.
