* Fix #817 * Fix #850 * Optimize math.floor/ceil/round with SSE4.1 * Results in a ~7-9% speedup on the math-cordic benchmark. * Optimized table.sort. * table.sort is now ~4.1x faster (when not using a predicate) and ~2.1x faster when using a simple predicate. Performance may improve further in the future. * Reorganize the memory ownership of builtin type definitions. * This is a small initial step toward affording parallel typechecking. The new type solver is coming along nicely. We are working on fixing crashes and bugs. A few major changes to native codegen landed this week: * Fixed lowering of Luau IR mod instruction when first argument is a constant * Added VM register data-flow/capture analysis * Fixed issues with optimizations in unreachable blocks --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
