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

Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.

Win32 only provides fetch-and-add, not add-and-fetch, and we don't really care. Rename the functions so the order of operations is clear.

On OS X it appears the mach exception thread and libdispatch queue threads occasionally get the SIGALRM from the itimer. Count those as foreign_thread_samples instead of letting the signal kill the process.

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.
