As the powerset grows, the cache needs to be keyed on both the base and
the full flags. While we're at it, we ensure that all FlatTypeMask
allocations go via the cache.

Collects files from `package:async_helper` and `tests/language`
that are generally useful, so that all test-related helpers are
in `package:expect`.
Moves the two libraries from `package:async_helper` into `package:expect`,
and the `tests/language/static_type_helper.dart` file too.
Deprecates `async_minitest.dart`, to follow `minitest.dart`,
expecting the Flutter use of it to have been fixed to not break
on deprecation (I believe Flutter no longer breaks builds on deprecations at all).
Patch 1 is the actual change.
Patch 2+4+8 is changing all existing references to the files.
Patch 6 ignores deprecation in files still using `async_minitest.dart`.
3+5+7+9 are updating this text to make the numbers match.
Then it's just test-expectations and small tweaks from there.

Because the old EnumSet was a wrapper object, some APIs performed
stateful updates. This CL also ensures that callers are now performing
their own state updates, just as if we were manipulating ints directly.

Work towards https://github.com/dart-lang/language/issues/2
The feature is well-specified at the issue, but I will also follow
up with a specification to check into the language repo.
This change implements the feature more-or-less from front to back
(because the back is very close to the front in this case :P; no
"backend" work in the VM, etc). Digit separators are made available
via a new experiment, `digit-separators`.
Care is taken to report a single error when an underscore appears in
an unexpected position (see new `separators_error_test.dart`).
Three test files are added:
* `separators_test.dart` is run with the experiment enabled, and has
no compile-time errors.
* `separators_error_test.dart` is run with the experiment enabled, and
has many compile-time errors.
* `separators_error_no_experiment_test.dart` is run with the
experiment _disabled_.

The `ClassRelation` concept is no longer needed as we are only using the CFE static type. All creations of "exact" and "this" types were already removed in an earlier CL so we are already always following the 'subtype' path.

Original change's description:
> [dart2js] Evaluate CFE consts as part of phase 0b (CFE linker).
>
> Constants are current evaluated in a few places during closed world generation, primarily as part of the ScopeModelBuilder. The scope visitor was modifying the AST which meant we had to emit a new dill with these evaluated constants along with the closed world results.
>
> This change instead evaluates the constants directly after linking the Kernel as part of the global transformations. This means we can update the ScopeModelBuilder to not mutate the AST at all as all constants are already simplified.
>
> A potential follow up here is to simplify the ScopeModelBuilder since all nodes should already be simplified if they can be, we should be able to avoid visiting some children.
>
> After this change we only directly create a single ConstantEvaluator, the one in `load_kernel`. The const simplifier also creates one and a follow up CL moves this to to run right after this new transformation.
>
> Note: Alternate versions of this CL tried to make the global transformation simpler by either:
> 1) Running the const evaluator indiscriminately on all expressions. This didn't work because it lead to exponential computation on constants set up as a DAG (see tests/language/const/constant_dag_test).
> 2) Only evaluating ConstantExpression nodes to update UnevaluatedConstants. This does not cover all the cases where the ScopeModelBuilder is modifying the tree and lead to a different compiler output.

The only constructor invocation of `NonConstantValue` is in the deserializer. Which means we're never creating any of these objects to serialize.

The only entities specific to the K- model are `KLocalFunction` and `KLocalTypeVariable`. I've copied these both (as is) to the J- model.
The only thing we "lose" here is the calls to `checkFamily` in `kernel/element_map_impl.dart`. Given how interchangable the 2 models were, this wasn't adding much value anyway.
Since there is still a distinction between the K- environment and J- environment, we can now think of that conversion as being between a `J` and `J'` environment where the semantics are slightly different (e.g. `J'` has closure conversion applied).
Using the same model also makes it easier to have more intermediate states of the `J` model. For example, we might keep around the `JLocalFunction` nodes until SSA and do closure conversion at that point instead.

FunctionSet is lazily initialized in the closed world. After this change it is never initialized during global inference. However, it is still used in SSA so we cannot fully remove it given these changes (even after linearized graph becomes the main algorithm).
Also remove unused methods/logic from FunctionSet itself. These are not called from anywhere in the compiler.

Suppose we have code like
if (isDevMode) {
// do foo
} else {
// do bar
}
where isDevMode is const (or can be evaluated as const). In particular,
isDevMode can be controlled by compile-time options, like
bool.fromEnvironment.
We currently eliminate the dead branch during SSA, but that means we do
the work of compiling dead code in the previous phases. Instead, we can
recognize that the condition is const (or effectively const) and
eliminate the dead AST subtree directly.

Effects of this change are minimal on a large application:
- ~9100 new members being tracked.
- +500KB closed world serialized output (.3% increase)
- No discernible difference in closed world runtime
- Heap space in global inference after closed world deserialization increase is <1MB.
- No change in JS output
These abstract members will be used by the new hierarchy-based dynamic call type graph linearization.
