Now that they're the only game in town we can give them the short names

vm: replace assert with FACTOR_ASSERT
...
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.

vm: separate 'current_gc_p' from 'current_gc'
...
The 'current_gc' handle doesn't need to be volatile, just the state of GC-ness

vm: don't need to save/restore FPU state when doing GC anymore, since we don't call nano_count() unless GC events are being recorded. If you want to record GC events with FP traps on, you're out of luck

vm: don't call nano_count() from the GC at all, unless GC event recording is on

Fix three problems discovered by running math.floats.env tests in a loop:
...
- Crash if allocating error triggers a GC from a signal/SEH handler
- Crash if GC runs with floating point traps enabled on Windows
- Floating point traps didn't prettyprint properly
