vegorov-rbx 271c509046 Sync to upstream/release/578 (#939) ... * Fixed gcc warning about uninitialized `std::optional` * Fixed inlining of functions when they are used to compute their own arguments In the new type solver: * Type families that are not part of a function signature cannot be resolved at instantiation time and will now produce an error. This will be relaxed in the future when we get constraint clauses on function signatures (internally) * `never` type is now comparable * Improved typechecking of `for..in` statements * Fixed checks for number type in `Add` type family * Performance was improved, with particularly large gains on large projects And in native code generation (jit): * We eliminated the call instruction overhead when native code support is enabled in the VM * Small optimizations to arm64 lowering * Reworked LOP_GETIMPORT handling to reduce assembly code size * Fixed non-deterministic binary output * Fixed bad code generation caused by incorrect SSA to VM register links invalidation --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Andy Friesen <afriesen@roblox.com>		2023-05-25 14:36:34 -07:00
