dart2js: should provide a complete implementation of dart:mirrors at runtime

[peter-ahe-google]

In r14469 we stubbed out some of how runtime mirrors can work in dart2js.

There are great technical challenges to overcome in implementing mirrors for dart2js, and we expect there wil be a non-trivial overhead for the most general usages.

At the time of writing, mirrors for are not being actively developed as the dart2js team is focusing on performance and language feature completeness. But patches are welcome!

The following should work now (in unminified code):

* Invoking instance methods.

* Setting instane fields.

* Getting instance fields.

I'm currently working on implementing support for reflecting on libraries.

https://codereview.chromium.org/15858005/ provides support setting and getting fields in library and class mirrors.

For those who are counting, this means that 4 out of 10 tests are passing in https://code.google.com/p/dart/source/browse/branches/bleeding_edge/dart/tests/lib/mirrors/mirrors_test.dart

Remember that this is not yet supported in minified code.
