The specification grammar has a rule for `initializerExpression` that
derives only `cascade` and `conditionalExpression`, whereas the
implementations allow throw expressions and assignments as well.
This CL broadens the grammar rule for `initializerExpression` such
that it derives the missing terms as well.

This CL changes the specification grammar Dart.g such that it allows
using `p.Function` to denote the built-in type `Function`. This is
necessary in the case where 'dart:core' has been imported with an
import prefix `p` (and it hasn't been imported without a prefix at the
same time). The corresponding spec update is in
https://github.com/dart-lang/language/pull/3492.

This language feature allows the user to declare a static type using
`extension type` syntax, for example:
extension type IdNumber(int i) {
operator <(IdNumber other) => i < other.i;
bool isValid(Some parameters) => ...;
}
This behaves similarly to a "wrapper" class:
class IdNumber {
final int i;
IdNumber(this.i);
operator <(IdNumber other) => i < other.i;
bool isValid(Some parameters) => ...;
}
However, at runtime, no wrapper objects are created; instead, an
instance of the extension type is represented directly by its
"representation type" (`int` in the above example), and methods like
`isValid` are resolved statically. This gives developers an
abstraction mechanism with the advantage of zero runtime performance
cost, since no extra heap space is required, and no extra instructions
are needed to convert between an extension type and its underlying
representation.
The disadvantage of using extension types as an abstraction mechanism
is that since no wrapper objects are created at runtime, the
abstraction can be bypassed using `dynamic`, runtime casts, or by
"laundering" the object through contravariant generic methods like
`List.add` (which are runtime checked in Dart). For example:
main() {
var id = IdNumber(1);
var list1 = <int>[];
List<Object> list2 = list1;
list2.add(id); // OK at compile time because `IdNumber` is a
// subtype of `Object`. OK at runtime because
// at runtime, `IdNumber` and `int` are
// indistinguishable.
int i = list1[0];
print(i);
}
Extension types are expected to be particularly useful for
low-overhead decoding of external data formats (such as JSON), and for
inter-operation with other languages (such as Javascript).

**This change cannot easily be reverted**: After reverting this change,
dart-ci-internal-release-bucket-breakglass must be broken by a member of
Dart EngProd and gs://dart-archive/channels/main/raw/latest must be
purged as well as gs://dartlang-api-docs/channels/main/latest.txt. This
operation would risk our release security and it is strongly preferred
if any problems can be fixed forward instead.
This change will upload the main channel builds to the main directory in
the dart-archive bucket instead of the be directory. The existing builds
remain where they are and the last version on the be channel remains
permanently frozen.
The downstream uses already have forward compatibility for the new
channel name. The Dart recipes respect the input channel name and output
to the release location by that name. The api.dart.dev service will
notice when the main channel pops into existence and switch
api.dart.dev/be to become api.dart.dev/main. The setup-dart github
action will likewise notice when the main channel starts existing.
The main channel is not an officially supported product since the builds
are not signed and tested and we don't advertise the existence of these
builds to our users. Ideally nobody would be broken by this change since
they shouldn't be using the main channel builds, but if they are, they
will have to rename the channel in their download links.
This change ensures that all the release branches and release channels
have the same matching names, which simplifies our infrastructure and
makes our releases easier to understand.

The Dart2JS team has agreed that this mode of compilation is no longer worth investing in at this time and its existence adds some overhead to other feature work so it is worth fully removing. In the future we may revisit this mode of compilation. Below is some more context for any future exploration in this space.
What didn't work with modular analysis:
- current modular analysis was computing impacts, which were dense (50% of the size of kernel)
- using it moved work to a modular phase, and cut Phase1 in half however end-to-end time was not better
- data overhead was very high
- it made it much harder to maintain invariants throughout the pipeline: the data is tightly coupled with the kernel AST, making it hard to make late modifications to the AST.
How to potentially make it better:
- make the data much more sparse
- make the data more independent from the kernel AST so that transformations are not breaking
- reduce the critical path in a more substantial way.
Note: We retain and ignore the commandline flags used for modular analysis in order to avoid breaking build pipelines that were passing them. We may remove these at a later date.

Many tests under `pkg`, like `pkg/js_ast` and `pkg/analyzer_cli` are
meant to run as unit tests in the Dart VM. These were also being run in
dart2js and causing flakiness because they took a long time to build on
our CQ.
Locally some of these tests compile in under 5s, but we see the
compile-time vary among the bots a lot. I've observed cases close to 30s
and some that reach the 1-minute timeout cutoff. Flakiness data show
that this is happening between 5-7% of the runs, especially on linux
bots.
This CL stops running these tests on the dart2js configuration by
changing which subset of the `pkg` suite is provided to dart2js. It also
adjusts the .status file to skip a few suites for convenience on local
testing only. This allows developers locally to run `test.py -n... pkg`
without worrying about filtering out skipped suites.
Addendum: after discussions on the CL we decided not to cmpletely drop
coverage of js_ast tests on JS to ensure it can be used in browser
environments in the future. To support this we made made the tests
cheaper by removing the dependency on package:test. They will now only
be run in a single configuration, which is all we need for this purpose.
We can reevaluate and remove this if we continue to see timeouts.
