Sync to upstream/release/565 (#845) We've made a few small changes to reduce the amount of stack we use when typechecking nested method calls (eg `foo:bar():baz():quux()`). We've also fixed a small bytecode compiler issue that caused us to emit redundant jump instructions in code that conditionally uses `break` or `continue`. On the new solver, we've switched to a new, better way to handle augmentations to unsealed tables. We've also made some substantial improvements to type inference and error reporting on function calls. These things should both be on par with the old solver now. The main improvements to the native code generator have been elimination of some redundant type tag checks. Also, we are starting to inline particular fastcalls directly to IR. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>

Sync to upstream/release/566 (#853) * Fixed incorrect lexeme generated for string parts in the middle of an interpolated string (Fixes https://github.com/Roblox/luau/issues/744) * DeprecatedApi lint can report some issues without type inference information * Fixed performance of autocomplete requests when suggestions have large intersection types (Solves https://github.com/Roblox/luau/discussions/847) * Marked `table.getn`/`foreach`/`foreachi` as deprecated ([RFC: Deprecate table.getn/foreach/foreachi](https://github.com/Roblox/luau/blob/master/rfcs/deprecate-table-getn-foreach.md)) * With -O2 optimization level, we now optimize builtin calls based on known argument/return count. Note that this change can be observable if `getfenv/setfenv` is used to substitute a builtin, especially if arity is different. Fastcall heavy tests show a 1-2% improvement. * Luau can now be built with clang-cl (Fixes https://github.com/Roblox/luau/issues/736) We also made many improvements to our experimental components. For our new type solver: * Overhauled data flow analysis system, fixed issues with 'repeat' loops, global variables and type annotations * Type refinements now work on generic table indexing with a string literal * Type refinements will properly track potentially 'nil' values (like t[x] for a missing key) and their further refinements * Internal top table type is now isomorphic to `{}` which fixes issues when `typeof(v) == 'table'` type refinement is handled * References to non-existent types in type annotations no longer resolve to 'error' type like in old solver * Improved handling of class unions in property access expressions * Fixed default type packs * Unsealed tables can now have metatables * Restored expected types for function arguments And for native code generation: * Added min and max IR instructions mapping to vminsd/vmaxsd on x64 * We now speculatively extract direct execution fast-paths based on expected types of expressions which provides better optimization opportunities inside a single basic block * Translated existing math fastcalls to IR form to improve tag guard removal and constant propagation

Sync to upstream/release/563 (#833) * Fix a bug where reading a property from an unsealed table caused inference to improperly infer the existence of that property. * Fix #827 We have also made a lot of progress on the new solver and the JIT. Both projects are still in the process of being built out. Neither are ready for general use yet. We are mostly working to tighten up how the new solver handles refinements and updates to unsealed tables to bring it up to the same level as the old solver. --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
