{
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

vm: clean up signal handling and add EXC_BAD_INSTRUCTION Mach exception handler for OS X, since signal handlers cannot change the stack pointer
