Move the generation of imported elements to the in-scope completion pass

Sorry for the long CL; once again I couldn't find a reasonable way to
split it up into smaller pieces.

This CL causes all of the elements from imports to be generated by the
new approach.

It does contain a new flag that is used to preserve the current
semantics when computing completions for Cider. I hope to be able to
make the new approach efficient enough that we can remove this flag,
but I can't realistically do that until more of the approach is
implemented.

I'm also not fond of the way it fails to handle conflicts in the import
scope. There's a TODO marking the places that would need to be changed,
but the current behavior is that if the same name N is imported from
two or more imports and they refer to different elements, the first one
found will be suggested and others won't. I don't think we want to
suggest any of them unless we also fix the imports so that the name
won't be conflicting. I'm not sure how we want to do that, but it needs
to work with whatever optimization approach we choose.

I think the changes to the tests are all positive, but please double
check that I haven't missed a good reason for the previous behavior.

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).
