Remove finished TODO entry

- final names TBD
- TODO: GDB commands for highest per-arena and total mem use

Steps towards figuring how to run tests spread out across multiple files

TODO: load test cases as python modules, or separate scripts using the source command?

Include them after the other scripts with -ex in GDB command line

- Commented out messages for memory allocations outside a parser context
- Commented out fallback for when a parser vtable can't be found in the dictionary, as that should be an error
- Added debug line printing the address that was not found in the vtable name->address dictionary
