* Handle translation between new and old log format styles
* Iteration
* Strip all backcompat
* Remove new parenthesis
* Handle directories in the test perf heuristic measurement
* Optional catch bindings!
* Always generate type & symbol baselines
* Accept changed shadowed baselines
* Accept brand new type and symbol baselines
* Allow `getTypeAtLocation` to return undefined in the type writer
* Accept baselines which had missing type information
* Bind container for dynamically names enum members so they may be printed
* Accept type/symbol baselines for enums with computed members
* First pass at reducing typeWriter memory overhead
* Use generators to allow for type and symbol baselines with no cache
* Accept new baselines for tests whose output was fixed by better newline splitting
* Hard cap on number of declarations printed, cache declaration print text
* handle differing newlines better still to handle RWC newlines
* Lower abridging count, accept abridged baselines
* Limit max RWC error output size, limit RWC type and symbol baseline input size
* Move skip logic into type and symbol baseliner to streamline error handling
* Accept removal of empty baselines
* Canonicalize path earlier to handle odd paths in input files
* Do canonicalization earlier still, also ensure parallel perf profiles for different targets do not trample one another
* No need to pathify again
* Keep a small reserve of tasks to not-batch, so all threads can have an initial task"
* Assign no weight to new tests, but still place them at the end of the list
* Remove batching on unittest thread
* Batch more things, improve output, use past test perf as a better heuristic for future test runs
* Fix merge sideeffect
* Fix typo
* Some tests depended on late execution
* Emulate mocha execution order
* Polyfill a synchronous done to handle that one unittest
* Accpept updates tsconfig baselines fixed by #18534
* Out with the old...
* Brave new world
* Throttle console output
* Batches test messages on large inputs initially
* Move parallel runner code into seperate files
