Add code heap introspection primitive to VM, and make a code-blocks word in tools.memory that wraps a useful interface around this. Add a lookup-return-address word and use this in tools.disassembler.utils

vm: modify-code-heap primitive now takes a pair of parameters, update-existing? and reset-pics?. If no generic words were changed, PICs do not need to be reset. If no existing words were redefined, the code heap doesn't have to be traced at all. Speeds up compilation of PEGs since those create lots of compilation units

Stop wearing monocle and use the term "entry point" instead of "XT" throughout VM and compiler; also remove two unused relocation types

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()

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

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
