[torque] Make torque declarations order independent

Torque semantic analysis is now a four-stage process:

 1. The TypeDeclarationVisitor introduces a TypeAlias for every
    TypeDeclaration* (or derived) in the Torque source, but does
    not process the TypeDeclaration* itself.
 2. All aliases are resolved in a dependency respecting manner.
    This CL also changes struct member resolution to happen at
    this point already. Types for classes are created, but their
    members are not resolved to allow classes to mutually reference
    each other in their field types.
 3. 'value' declarations (macros, etc.) are processed.
 4. Members of classes are processed.

V8 JavaScript Engine

V8 is Google's open source JavaScript engine.

V8 implements ECMAScript as specified in ECMA-262.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

V8 can run standalone, or can be embedded into any C++ application.

V8 Project page: https://v8.dev/docs

Getting the Code

Checkout depot tools, and run

    fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
