Sync to upstream/release/630 (#1295) ### What's new * A bug in exception handling in GCC(11/12/13) on MacOS prevents our test suite from running. * Parser now supports leading `\|` or `&` when declaring `Union` and `Intersection` types (#1286) * We now support parsing of attributes on functions as described in the [rfc](https://github.com/luau-lang/rfcs/pull/30) * With this change, expressions such as `local x = @native function(x) return x+1 end` and `f(@native function(x) return x+1 end)` are now valid. * Added support for `@native` attribute - we can now force native compilation of individual functions if the `@native` attribute is specified before the `function` keyword (works for lambdas too). ### New Solver * Many fixes in the new solver for crashes and instability * Refinements now use simplification and not normalization in a specific case of two tables * Assume that compound assignments do not change the type of the left-side operand * Fix error that prevented Class Methods from being overloaded ### VM * Updated description of Garbage Collector invariant --- ### Internal Contributors Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> 2024-06-14 21:21:20 +01:00			`std::optional<TypeId> generalize(NotNull<TypeArena> arena, NotNull<BuiltinTypes> builtinTypes, NotNull<Scope> scope, NotNull<DenseHashSet<TypeId>> bakedTypes, TypeId ty);`
