Clean up how negated integer literals are type inferred.

Previously, when upon reaching the integer literal, we would check if
the parent was a PrefixExpression with an operator of `-`, and if so,
use the context type of the PrefixExpression to decide whether to do
an int->double conversion.  This CL moves the logic to the
PrefixExpressionResolver; we now pass down the appropriate context
when visiting the integer literal.

This makes the context handling for negated integer literals less of
an odd exception.

This is part of a larger effort to elimiate the use of
InferenceContext.getContext and InferenceContext.setType entirely.

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).
