Tess Strickland be4d469e38 [pkg/dart2native] Refactor MachO parsing.
* Move parsing functions to static methods of the classes that
  represent the data being parsed.

* Move calculations for adjusting offsets in load commands into the
  corresponding classes.

* Make function to insert a new payload segment an instance method
  of MachOFile.

* Remove unnecessary abstractions and definitions for MachO load
  commands that we don't need to parse.

These refactorings are being done to make later changes easier to
review, by first lifting the initial refactorings out into a
separate CL.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

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).
