Dart2js allows to declare JS-interp members, even if the enclosing library
doesn't have a JS annotation. This relaxes DDC to do the same.

This adds a new messages kind 'info' to the CFE for showing general
information during compilation. A 'configuration' options is added
to `CompilerOptions` for telling the CFE how it is run.
The configuration 'compile' is added for when the CFE is invoked to
produces an "executable" as when running `dart compile`. When
configuration is set, the CFE emits an info message about the
null safety compilation mode.
Support for `dart compile exe` and `dart compile js` is added in this
CL. Support for `dart compile kernel|app-jit|aot` is not included.

This consists of a few combined changes:
* support `@Native` on tests: This entails calling registerExtensions
on user code, but only when running on native tests (which are explicitly
added to an allow list).
* support for invoking external top-level methods also on native tests.
* support for running `applyExtension` later in tests. This is because
tests introduce the JavaScript definitions after the calls to
registerExtensions happen. Note: this wouldn't be necessary if we one
day change how tests are loaded (e.g. if we can load the JavaScript
portion of the test before the module compiled by dartdevc is loaded).
That would entail more infrastructure work and given that this is only
used for ~200 tests, it doesn't seem worthwhile at this time.
* ensure extension symbols are also stored in `dartx.*` from a native
test. This is to ensure dynamic calls are fully supported.
* changes to the dart2js runtime to ensure the test code can run in both
dartdevc and dart2js with the same API.
* one updated test: all native tests need to be updated and I'll follow
up with those, but the changes on this test are included in this CL to
illustrate how this all fits together.
After this change (and parent changes), you can now run:
./tools/test.py -m release -c dartdevk -r d8 dart2js/native/native_checked_arguments1_frog_test

This reverts commit 825f56c6aa.
Both ddc and dart2js keep a set of native class names to make sure
@JS() classes don't conflict. Instead of processing native classes
for every component, this CL caches the set of native classes. This
should address the recompile time issues related to the original
revert.

During expression evaluation, we are collecting all variables in
all scopes that contain the current breakpoint line, and adding them
as available in current scope, which makes variables declared below
the current breakpoint line declared but undefined in JavaScript.
There is one exception to this seen so far - a variable
declared on the current breakpoint line might appear as not declared
in JavaScript and cause expression evaluation not to work due to
JS compilation errors.
This change fixes the issue by not collecting variables that are
declared on or after the current breakpoint line, making them undeclared
in dart (which also is correct according to dart scoping rules).

This CL adds stub for each concrete mixed in member into mixin
applications. The body of the stub calls the original member via
a super call.
This addition means that resolution of super access now use the
stub and not the original declaration as the target, which means
that it will be correct even when mixed in members are cloned. For
this reason, dart2js no longer needs to perform its own super
member resolution.
When a super call targets a mixin super stub (after cloning) it
can be optimized away by redirecting the call to the `stubTarget`
of the call. This optimization is performed in dart2js.
Since dart2js now uses the correct super target, its runtime
mixin application needs to avoid overriding members already
declared in the mixin application. These members are the
forwarding super stubs which ensure that correct runtime types
when members with covariant parameters are implemented.

Hopefully this will avoid bugs in the future if the lowering of

This does not change the current optimization for late variables
with list literal initializers. That lowering introduces a final
variable that is not marked as late that appears as the receiver

Before Null Safety, `_EventStreamSubscription.cancel()` used a trick
to run with synchronous timing even though it was typed to return a
`Future`. During the migration of the SDK to support Null Safety it
kept the synchronous timing in weak mode, but was changed to
asynchronous in sound mode so that the behavior matched the method
signature. In hindsight, changing the timing when opting into Null
Safety is problematic:
* A shared package has no control over what mode it runs in. Libraries
may be opted in and run their tests with sound null safety but the
apps they are used in could still be running in weak mode. This
results in library unit tests that behave differently than the
production app that deploys the code.
* This codepath can be triggered by EventTarget.dispatchEvent() from
dart:html which should have synchronous timings for the event
listeners before returning to the calling code. The asynchronous
timing when running with sound null safety is inconsistent with the
browser API.
This change reverses that migration decision and keeps the synchronous
timing in both modes. To support this in sound mode it returns a
special future value that is internal to the SDK and known to be used
for synchronous timing.
This change also removes the workaround introduced in DDC to avoid
warning/failing when `_EventStreamSubscription.cancel()` returned
null and the extra warnings/errors features were enabled in weak
null safety mode.

This change selectively containerizes many top-level JS constructs. Containers maintain a max size of 500 elements for JS optimization purposes. Containers with unspecified key names are emitted as JS arrays. Containerization occurs for symbols when the number of top level symbols exceeds 600 but is automatic for other constructs. However, containerization in the Dart SDK only happens for web libraries for runtime optimization purposes.
Two types of common DDC constructs result in their capture by all subsequent closures:
* Self-referential variables:
var selfLambda = () => selfLambda = "foo";
* Variables referenced in sister functions:
var unused = "foo";
function unusedF() => console.log(unused);
The following are now accessed through an additional level of indirection:
* Type generators (frequently follow the self-referential variable pattern)
* Constant cache variables
* Dart private names (used for virtual method dispatch)
* Top-level string constants (such as URI strings)
Additional changes:
* The ModuleItemContainer handles automatic renaming of arbitrary top-level JS expressions. This is a multimap that maps keys of an arbitrary type to JS key-value pairs.
* The CacheTable and TypeTable have been unified. The old cache table seemed to have been created with a similar use case as the ModuleItemContainer but had become too specialized.
* The new TypeTable unifies much of the logic for emitting types, including explicitly separating the discharge of types dependent on free variables (such as generic types, generic functions, and their bounds) from types that are fully bound.
Reduces top-level captured variables in the SDK by ~5711 per recursive callback.
