Gabriel Terwesten e2d6cb69fb Reland "[vm/compiler] Optimize switch statements" 
This is a reland of commit f5228127f8

Original change's description:
> [vm/compiler] Optimize switch statements
>
> Switch statements that either contain only integers or only enum values of the same type can be optimized.
>
> Depending on the number of switch expressions and the number of holes that the range of switch expressions contains, either a binary search or a jump table is used.
>

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).
