[vm/ffi] Exposes an iterable `Array.elements` For the arrays of the Int/Uint/Float/Double types this has been implemented straight in the ffi_patch.dart file and `elements` returns a typed-data list view on the original data backing the array. The Bool and Pointer arrays return helper classes from their `elements` getter. These helper classes implement the `List` interface utilizing the `operator []` implementation of the underlying arrays. This is also implemented directly in the ffi_patch.dart file. The `elements` getter for array arrays is rewritten in the CFE (use_sites.dart) to instantiate a helper class to which the size of a single element of the array is passed (this information is not available in ffi_patch.dart, hence the rewrite in the CFE). The helper class implements the `List` interface and performs some pointer arithmetic with the provided element size to implement its methods. The `elements` getters for struct and union arrays are also rewritten in the CFE to instantiate a helper class to which a constructor tearoff for instantiating the underlying struct/union type is passed. The helper class also implements the `List` interface and uses the provided constructor tearoff to create instantiated structs/unions of the elements in the list. Last, but not least, the `elements` getter for abi-specific integer arrays is also rewritten in the CFI to instantiate a helper class to which a closure is provided to load abi specific integers from the underlying array data structure.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
See LICENSE and PATENT_GRANT.
