[cfe][InternalNodes] Avoid use of .parent during inference This avoid the use of .parent on the AST from the body builder. The prepares for using a separate AST from the body builder which doesn't have a parent pointer. The changes pass the information from the parent through the visiting; from variable declarations to determine whether a variable declaration can be converted into an expression statement for effect, and on analysis of subexpressions in the shared type analyzer to determine whether the analyzed expression should be coerced.

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.
