...
The code reads better if the safepoint_state methods and
attributes (sample_counts and safepoint_fep_p) are moved to the vm
class.

vm: count samples from foreign threads

vm: groundwork for sampling profiler
...
Set up the state necessary to collect samples. We still need to add GC support for walking the sample set, and the compiler needs to register GC roots before safepoints as well. We also need primitives to expose the data to Factor for reporting.
