How to find class instantiations?

I want to find all places where a class is instantiated with the 'new' keyword. How can I do it?

I've found that when a class has a constructor I can use 'Find Usages' on it and all instantiations are found. But if a class has no constructor then there is nowhere I can invoke this search on. Trying to find usages on the class name returns all occurrences of the class in any form whereas I just want to find its instantiations. How can I do it regardless of whether the constructor exists or not? There is a hacky way of temporarily creating an empty constructor just for this but this seem absurd.
