base: Add operators to SatCounter

Add shift, add and subtract assignment operators, as well as
copy and move constructor and assignments to SatCounter, so
that it they can be used by the prefetchers.

Also add extra useful functions to calculate saturation
oercentile so that the instantiator does not need to be aware
of the counter's maximum value.
