Use _exit() in Reporter::FatalError

Browse source 
Using exit() here may generally not work well since:

* That will result in calling global destructors

* We have global state that we potentially modify at run-time and
  are in the middle of modiying at the time the FatalError occurs.
  E.g. out-of-memory is one situation where it's likely we could
  call the dtor of an object in which operation on it's internal
  state is no longer consistent/safe.
