With this CL the time is measured from when the streaming decoder is
finished until the time when the compilation of all functions of the
streamed module is finished. If the streaming decoder finishes second,
the time gets recorded negatively. This timer should allow us eventually
to check whether the assumption that Liftoff compilation is faster than
downloading module bytes is correct.
