Stop calling InferenceContext.getContext() from migration tool. In a follow CL, I'm planning to try to pass inference contexts around on the stack rather than using static calls to InferenceContext. This should be both more performant (since it will use less memory and won't require map lookups) and easier to debug. To prepare for this I want to get rid of migration engine's use of InferenceContext.getContext(). It turns out that the only contexts needed by the migration engine were (a) the context of an expression passed to modifyExpressionType(), and (b) the context of any binary `??` expressions that are its parent. I've addressed (a) by passing the context as a parameter to modifyExpressionType(), and I've addressed (b) by creating an additional hook that records the context of any binary expression at the time it is entered.

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).
Dart is free and open source.
