* Added a limit on how many instructions the Compiler can safely produce (reported by @TheGreatSageEqualToHeaven) C++ API Changes: * With work started on read-only and write-only properties, `Property::type` member variable has been replaced with `TypeId type()` and `setType(TypeId)` functions. * New `LazyType` unwrap callback now has a `void` return type, all that's required from the callback is to write into `unwrapped` field. In our work on the new type solver, the following issues were fixed: * Work has started to support #77 and #79 * Refinements are no longer applied on l-values, removing some false-positive errors * Improved overload resolution against expected result type * `Frontend::prepareModuleScope` now works in the new solver * Cofinite strings are now comparable And these are the changes in native code generation (JIT): * Fixed MIN_NUM and MAX_NUM constant fold when one of the arguments is NaN * Added constant folding for number conversions and bit operations * Value spilling and rematerialization is now supported on arm64 * Improved FASTCALL2K IR generation to support second argument constant * Added value numbering and load/store propagation optimizations * Added STORE_VECTOR on arm64, completing the IR lowering on this target
