AFAIK Windows has no equivalent to setitimer. We'll probably need to use a thread that periodically pauses and samples the main VM thread.

vm: count samples from foreign threads

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.
