You can broach it as trying to get some help in navigating the situation versus trying to get this guy in trouble
Look, when you rely on others to fight your battles (ie HR), you're setting yourself up for failure. HR won't do anything against a powerful employee. YOU will be labeled a problem employee and the manager will make sure that he finds something you've done to get you fired (and everyone has something). If HR would actually do anything, then the manager wouldn't behave the way he is.
I knew a guy who had a manager like yours. He made sure to make the guy's life miserable until he stopped. The manager's files mysteriously disappeared. His computer stopped working for mysterious reasons. Etc... Nothing the boss could do about it, since the employee was careful about not getting caught and had plausible deniability. When his manager confronted him, all he did was deny, deny, deny... He explained that the manager had several people in the department that didn't like him and offered to "keep an eye out" for anyone who might be messing with the manager.
