Fixes#34167. This implements the Dart 2 mixin proposal
(https://goo.gl/KEKQyv) for DDC. When the mixin is applied, a class
is created for the application that extends the correct superclass
and has all of the instance members, so `super` works correctly.
This also fixes a few minor issues in Analyzer's (mostly complete)
implementation:
- InterfaceType.isObject now returns false for Dart 2 mixins.
- Least upper bound calculation recognizes mixins are not Object.
- Interface of the mixin now implements its superclass constraints.
- Mixin superclass constraints are checked against the superclass and
all previously applied mixins (if any); this keeps it working with
the subtype fix above, and also prevents a not-yet-applied mixin
from satisfying the constraint
The language_2/mixin_declaration tests were updated with a few minor
fixes now that we can run Analyzer/dartdevc to test them.
This change implements super mixins for DDC's Kernel backend (DDK)
too. This will be enabled once Kernel adds a flag to recognize which
Class nodes are mixins (vs normal classes).

We don't want to silently pass tests that think they are async when
the test framework doesn't know it's async.

My initial goal was just to move some of the HTML tests off unittest,
but that ended up slurping in some other changes as well. I haven't
finished going through all of the tests, but this puts the
infrastructure in place and fixes a batch of them. I'll do more next.
Changes:
- Add a "minitest" package. This shims just enough of the unittest/test
API to make it easy to swap it out for unittest without having to
rework the entire test.
- Go through the HTML tests from A-J and change them to use minitest
when possible. The ones that aren't possible use asynchrony.
Minitest doesn't support async tests (yet, maybe).
- Triage those tests and enable ones that are passing. Mark them failing
if failing. Filed a couple of tracking bugs for the common issues,
but for other cases, I just left a comment.
- In the process of this, I went ahead and make some of the affected
tests strong mode clean if they weren't already and it was easy.
- Synchronize changes between dev_compiler's fork of expect and
pkg/expect. We'll want to unfork those at some point. D-:
This gets dev_compiler from 1985 tests to 2042.

Expect.throws calls its first argument, f, with no arguments.
If f isn't callable in this way, the act of calling would throw, and this throw would be considered as makeing the Expect.throws succeeede.
Now we check the argument first, and call it outside the try/catch if it's not callable. This was already caught in checked mode, but we shouldn't accept a false positive in unchecked mode either.
