vm: move dispatch_signal_handler to cpu-x86.cpp
...
The new signal handler dispatch is logic is CISC-centric; defer fixing it until we find someone who cares

vm: remove signal_from_leaf flag

Now that the resuming from the signal handler works within leaf procedures, the flag is no longer necessary.

vm: fep on SIGINT or SIGQUIT instead of exception
...
It's not robust currently to raise an exception because a lot of our code that isn't already written with exceptions in mind breaks. Also, a signal is likely to be received by an FFI callback installed on the IO multiplexer, which will cause Factor to die since the callback cannot handle the exception. We need a more robust solution to dealing with SIGINT.
Also lay some groundwork for counting profile samples and reporting non-interrupting asynchronous signals.
