* Work toward affording parallel type checking
* The interface to `LazyType` has changed:
* `LazyType` now takes a second callback that is passed the `LazyType&`
itself. This new callback is responsible for populating the field
`TypeId LazyType::unwrapped`. Multithreaded implementations should
acquire a lock in this callback.
* Modules now retain their `humanReadableNames`. This reduces the number
of cases where type checking has to call back to a `ModuleResolver`.
* https://github.com/Roblox/luau/pull/902
* Add timing info to the Luau REPL compilation output
We've also fixed some bugs and crashes in the new solver as we march
toward readiness.
* Thread ICEs (Internal Compiler Errors) back to the Frontend properly
* Refinements are no longer applied to lvalues
* More miscellaneous stability improvements
Lots of activity in the new JIT engine:
* Implement register spilling/restore for A64
* Correct Luau IR value restore location tracking
* Fixed use-after-free in x86 register allocator spill restore
* Use btz for bit tests
* Finish branch assembly support for A64
* Codesize and performance improvements for A64
* The bit32 library has been implemented for arm and x64

* Fixed unions of `nil` types displaying as `?`
* Internal normalization now handles class types which can make
previously failing (incorrectly) sub-typing checks to succeed
- Remove type definitions of
`utf8.nfcnormalize`/`nfdnormalize`/`graphemes` that aren't supported by
standalone Luau library
- Add `lua_costatus` to retrieve extended thread status (similar to
`coroutine.status`)
- Improve GC sweeping performance (2-10% improvement on allocation-heavy
benchmarks)
