This change reverts https://dart-review.googlesource.com/c/sdk/+/341020.
The reverted CL removed tests from `tests/language` that contained
legacy code (code with a language version less than 2.12). The primary
purpose of the removal was to unblock removal of legacy support from
the analyzer. It seemed safe to do because legacy code isn't supported
anymore, and no legacy code exists in google3 anymore. However,
several of those tests exercised important "weak mode" runtime
semantics of the web and VM platforms. See discussion at
https://dart-review.googlesource.com/c/sdk/+/341020/comments/bce31aa1_f5392ce1
for details.
This CL restores the deleted tests. Fortunately, since all the
restored tests are annotated with `Requirements=nnbd-weak`, they will
be skipped on the analyzer (thanks to
https://dart-review.googlesource.com/c/sdk/+/342080), so restoring
them no longer gets in the way of removing legacy support from the
analyzer.

Now that we no longer need to support legacy (pre-2.12) code in
google3, we don't need to test our support for it either.
Most of our language tests for legacy code were in `tests/language_2`
and have already been deleted; this CL addresses the few tests that
remain in `tests/language`, mostly dealing with "mixed mode" scenarios
(i.e., interactions between legacy code and null safe code).

We rely on the result of the `ConstantVisitor` to indicate whether we have an error or a valid constant value.
This CL changes `evaluationResult` to be a `Constant` and changes error reporting to occur at a POE for evaluating a constant.
Last few chunks of cleaning up the constant evaluator, woo!

evaluateConstructorCall now returns a Constant, which means evaluation may be cut early in some places if there's an error. However, some code generators rely on _InstanceCreationEvaluator to complete, and so there's no _major_ changes to the design right now (and some small additions to avoid breaking many tests).
This CL is just the framework for the "return Constant" design and will be the base for reporting better errors in constructor invocations.
These changes already show that we cut some amount of over-reporting in our existing language and unit tests, which is a step in the right direction.

Some of these should be tests but were missing "_test". Others seemed
to simply be dead code. Some should have been referenced but there were
mistakes in the imports in other files.
