* Fixed exported types not being suggested in autocomplete * `T...` is now convertible to `...any` (Fixes https://github.com/Roblox/luau/issues/767) * Fixed issue with `T?` not being convertible to `T | T` or `T?` (sometimes when internal pointer identity is different) * Fixed potential crash in missing table key error suggestion to use a similar existing key * `lua_topointer` now returns a pointer for strings C++ API Changes: * `prepareModuleScope` callback has moved from TypeChecker to Frontend * For LSPs, AstQuery functions (and `isWithinComment`) can be used without full Frontend data A lot of changes in our two experimental components as well. In our work on the new type-solver, the following issues were fixed: * Fixed table union and intersection indexing * Correct custom type environments are now used * Fixed issue with values of `free & number` type not accepted in numeric operations And these are the changes in native code generation (JIT): * arm64 lowering is almost complete with support for 99% of IR commands and all fastcalls * Fixed x64 assembly encoding for extended byte registers * More external x64 calls are aware of register allocator * `math.min`/`math.max` with more than 2 arguments are now lowered to IR as well * Fixed correctness issues with `math` library calls with multiple results in variadic context and with x64 register conflicts * x64 register allocator learnt to restore values from VM memory instead of always using stack spills * x64 exception unwind information now supports multiple functions and fixes function start offset in Dwarf2 info
