* Optimized operations like instantiation and module export for very large types In our new typechecker: * Typechecking of function calls was rewritten to handle more cases correctly * Fixed a crash that can happen after self-referential type is exported from a module * Fixed a false positive error in string comparison * Added handling of `for...in` variable type annotations and fixed issues with the iterator call inside * Self-referential 'hasProp' and 'setProp' constraints are now handled correctly In our native code generation (jit): * Added '--target' argument to luau-compile to test multiple architectures different from host architecture * GC barrier tag check is skipped if type is already known to be GC-collectable * Added GET_TYPE/GET_TYPEOF instructions for type/typeof fast-calls * Improved code size of interrupt handlers on X64
