[ddc] Rename variable used to store late value

Late local variables are lowered by the CFE into a local:
* backing store variable
* get method
* set method
* isSet local variable (optionally when the type is nullable)

This change updates the name in JavaScript used for the backing store
variable to match the name for the late variable from the original
source. It also updates the scope information passed for expression
evaluation to remove the lowered name and replace it with the original
so evaluations will work as well.

The name change avoids the hiding performed by the debugger on
recognized temporary names so it appears in the list of local variables.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

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).
