vm: a stack underflow inside a primitive could leave a data root in an uninitialized state; if allocating the thrown underflow error triggered a GC, the GC would visit a garbage pointer

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

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
