* 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
* Added luau-compile executable target to build/test compilation without
having full REPL included.
In our new typechecker:
* Fixed the order in which constraints are checked to get more
deterministic errors in different environments
* Fixed `isNumber`/`isString` checks to fix false positive errors in
binary comparisons
* CannotCallNonFunction error is reported when calling an intersection
type of non-functions
In our native code generation (jit):
* Outlined X64 return instruction code to improve code size
* Improved performance of return instruction on A64
* Added construction of a dominator tree for future optimizations
