Run PreallocationTest as a performance test. Three tests are filtered because the
measurements are too close to the precision of the framework.

results = runperf('PreallocationTest');

To instruct the framework to automatically loop through the measured code and average
the measurement results, modify PreallocationTest to use a keepMeasuring-while
loop instead of startMeasuring and stopMeasuring.
