validation: Test CPU performance

Browse Source 
Measure the runtime of 1000 no-operation instructions.  This may help to
investigate runtime measurement variations which do not result from code
generation or source code changes.

The runtime measurement of a function which does nothing and just
returns gives an estimate of the measurement overhead.

Update #3716.
