Today, most tests that touch on a behavior variation end up
skipping expectations or the entirety of a test for some
testing configurations. Moving forward, we'd like skip less
and try to account for the behavior variations if that's
reasonable.
This CL shows an approach to improve our test coverage for
behavior variations. We introduce two new methods to
[Expect] that allow us to conditionally check that a
function throws, depending on variation predicates.
The CL changes expectations for errors that don't occur
when dart2js omits parameter type checks or implicit
downcasts.
Note: originally I had the intention to introduce a name
parameter to `Expect.throws` and `Expect.throwsTypeError` to
avoid introducing a new API. However, because these APIs are
used for testing core language features, such as function
parameters themselves, we decided to keep the use of
features in these APIs as simple as it can be.

This updates tests to start using `checkedParamters` and
`checkedImplicitDowncasts` instead of `dart2jsProductionMode`

Mark tests that contain errors about using a class as a mixin to use
language version 2.19 where that's not an error.
This may not fix all of the tests because it's the language version of
the library where the class is declared that matters, not where the
class is used as a mixin. But most tests have all of their declarations
in the same library, so this should fix most.

language/covariant/type_parameter_test.dart performed a tearoff which
should incur a run-time error (because the dynamic type of the
tearoff is not a subtype of the static type, so it would be a
soundness violation to pass that value on to the next step of
evaluation).
