Revert "[dart2js] Defer deserialized CodegenResults by members."

This reverts commit a547cfc0969ea9baca14529670dd553ad810131c.

Reason for revert: With 15 shards this ends up holding too much serialized data and causes an increase in memory usage.

Original change's description:
> [dart2js] Defer deserialized CodegenResults by members.
> For large applications only ~60% of these objects are used. This defers their deserializtion until they're accessed in the codegen member map.
> In local testing on large applications this saved ~200MB of memory usage in the linker phase.

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).
