Why isn't this code removed too?

The compiler stats use timers.

Ditto.

https://codereview.chromium.org/1375343002/diff/1/runtime/vm/timer.h#newcode144
runtime/vm/timer.h:144: class PauseTimerScope : public StackResource {
While this class isn't used anymore, I decided to leave it in here in case I
want to use it for compiler stats later.
