Fixed events benchmark postEvent function

The postEvent function was causing problems in Symbian because it
couldn't handle multiple iterations of the benchmark.

- Moved event allocation inside QBENCHMARK so that each iteration will
  have a fresh event object.
- Added resetting of the PingPong counters inside QBENCHMARK.
- Used QTestEventLoop::instance().exitLoop() instead of
  QCoreApplication::quit() to make the cases beyond first
  to actually test something meaningful.
- Added a "first time" case to postEvent_data, as the first time the
  event loop is used it takes much longer that the subsequent times,
  at least in Symbian, so that skewed the results.
