vm: if an aging GC is triggered while uninitialized code blocks are in the code heap, the code heap remembered set becomes out of date, resulting in code blocks pointing at invalid data

vm: big overhaul of non-optimizing compiler
...
- change some primitives into sub-primitives: fixnum+ fixnum- fixnum* inline-cache-miss inline-cache-miss-tail
- rename some relocation types for clarity
- some other minor re-organizations and cleanups

Get modify-code-heap working if stack traces are stripped (but then it won't update existing code blocks), and rename code_heap::code_heap_free() to code_heap::free()

RT_HERE now takes its argument from the literal table rather than the parameter table, reducing image size further

Big cleanup of literal table and relocation-related code
...
- new way to iterate over instruction_operands cleans up relocation code
- move some methods out of the VM class to clean up code
- if debugging is on, die earlier if attempting to allocate inside GC
- callback heap entries are now code_blocks
- replace block_granularity with data_alignment
