[esan|wset] Add 8-level working set snapshot accumulation
Summary:
Adds a new option -snapshot_step controlling the frequency distribution for
an 8-level series of samples using each bit of each shadow byte.
Implements accumulation from each level to the next higher level at the
specified frequency.
Adds storage of the 8 series of samples using CircularBuffer instances.
Fixes an error in the circular buffer data structure where a static
object's destructor will be called too early.
Prints the results out at the end in a simple manner to give us something
to start with.
Updates the workingset-samples test to test the new feature.
