[parser] Create parser equivalence test suite for ensuring that files parse 'the same'

This CL creates a new test suite running through *.equivalence_info
(yaml) files where one specifies a number of files that are supposed to
parse 'the same' in the sense that it gives 'the same' listener events
modulo whatever the yaml file specifies is ok is not the same.
This could for instance - and is in the tests added here - be to not
include data after the parenthesis (as it often includes tokens),
ignoring `handleParenthesizedExpression` (as for instance `a < b` and
`(a < b)` should probably parse the same and ignoring
`handleRecoverableError`.

This might be a bit basic, but as future needs come up we can make this
fit our needs.

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).
