Threads.checkNotInterrupted() throws InterruptedException or similar

[GoogleCodeExporter]

Suppose I'm implementing a CPU-expensive background operation, and I need to 
cancel it fast if the thread running it gets interrupted.
I would repeatedly write:

if(Thread.interrupted())
    throw new InterruptedException();

It would be nice to have that as a library method, such as:

Threads.checkNotInterrupted();

That would just implement the same behavior of interruptible system calls, so I 
think it may deserve getting into Guava.

See http://docs.oracle.com/javase/7/docs/api/java/lang/InterruptedException.html

Chris found a surprising number of people who do this check. However, is it 
worth introducing an entirely new class (Threads) and a new method just to 
avoid 3 lines of code (that's explicitly recommended in InterruptedException 
already?).

Naming this method would be tricky too.

Yeah, a reasonable request, but it's a small enough snippet of code that I'd 
prefer to avoid introducing a new class.
