vm: reinitialize all_blocks from scratch after gc
...
Faster and more likely to be correct than trying to fixup the existing set

vm: initialize all_blocks map from image
...
um, code blocks from the image need to go in the set too

vm: keep a set of all code_blocks in the code_heap
...
This way looking up code blocks by return address is an O(log n) set lookup rather than an O(n) linear scan.

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
