vm: new GC policy: mark sweep after N megabytes promoted, mark compact if tenured space cannot fit nursery+aging in one contiguous block. N = 32 on 32-bit and 64 on 64-bit

vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead

Big VM cleanup
...
- Move forward declarations of 'struct factor_vm' to one place
- Rename template parameters from T and TYPE to descriptive names. New convention: CamelCase for template parameters
- Change some higher-order functions taking function pointers into templates, and define classes overriding operator(). There's a bit of new boilerplate here but its more consistent than the old mish-mash approaches
- Put GC state into a gc_state struct
- Use exceptions instead of longjmp for non-local control transfer in GC
- In code GC, instead of interleaving code block tracing with copying, add code blocks which need to be revisited to an std::set stored in the gc_state
