[esan|wset] Iterate all memory to compute the total working set
Summary:
Adds iteration of all application memory in an efficient manner using
shadow faults. Shadow memory starts out inaccessible and we mark it
writable one page at a time on each fault when the instrumentation touches
it. This allows iteration over just the mapped shadow memory, saving
significant time.
Adds a process-end iteration and pretty-printing of the final result.
Adds a new test and updates the existing tests.
