I've also added some runtime checks to
`tests/language/patterns/object_pattern_inference_test.dart` to verify
that the object patterns match when they should match and don't match
when they shouldn't; this helps verify that not only has the front end
inferred the correct type for the object patterns, but it has also
stored the correct type in the kernel representation.

Changed the classes to store induced modifiers on `isBase`, `isFinal`, and `isInterface`. If one of these getters are true and `isSealed` is true, then we assume it's an induced modifier. (Since a class or mixin cannot be both sealed and another modifier).
There's a subtle change here where the induced modifiers are only marked on sealed classes which means that classes that subclass/subtype non-sealed classes won't get any base or final errors. This will also affect how lints will be reported -- at the next erroneous subtype and not downstream from that type.
Also, the context messages now point to the class with the explicit modifier inciting the error.

This reverts commit 49f85335d5.
Reason for revert: Fixes the original breakage by adding an explicit
cast for the map function that's used to compute positional args
of the stub. Adds refactoring to better separate out the logic
between procedure-level and invocation-level lowering configs.
Also refactors optional argument functions so that they can use the
invocation-level lowering configs created in this CL. Also fixes
a small issue where object literal constructors wouldn't work in
dart2js if the surrounding library didn't have a @JS annotation.

This turns on the flags for these two language features and makes
them generally accessible.
Doing so causes a number of tests to fail, but the failures are
approved and there are filed issues for them. Most of the
failures are minor or only affect code using the new language
features.
This CL:
- Enables the features in experimental_features.yaml.
- Re-generates all of the various files generated from that.
- Makes some analyzer and front end changes that this CL
inherited from Paul's original CL flipping all of the 3.0
feature flags. I don't know what these changes are about, but
I assume they are necessary.
- Pins a couple of tests to 2.19 since they deliberately test
behavior that is specific to 2.19. (For most test changes, I've
landed them separately, but there are a couple of stragglers
in this CL.)
This doesn't enable "class-modifiers" or "sealed-types" and doesn't
include the core lib changes related to those.

This avoids virtual calls for `runtimeType` (unless the user overrides
it) and `_runtimeType` (since the internal categorization is now done
using the table instead), which saves a huge amount of space in the
global dispatch table.
It also fixes record runtime types, which now use the masqueraded
types for its fields, rather than the (possibly user-overridden)
`runtimeType`.
A masquerade case was missing for `Type`, which has been added.

`hashCode` requires that equal objects have the same hash code.
However it doesn't (and cannot) require that inequal objects have
different hash codes. Remove the invalid check.
This makes the test pass on dart2wasm, which currently implements
closure hash code as:
// Simple hash code for now, we can optimize later
@override
int get hashCode => runtimeType.hashCode;
Note: this change alone does not make the whole file pass with
dart2wasm, there's another (unrelated) issue which will be fixed
separately.

This may not fix all of the tests because it's the language version of

class is used as a mixin. But most tests have all of their declarations

This change improves the fallback exhaustiveness algorithm so that it
also takes advantage of the old, pre-patterns exhaustiveness logic for
enums. This ensures that the fallback exhaustiveness algorithm won't
seem like a regression to users who are used to the old pre-patterns
behaviour. This required extending the old algorithm to handle
new-style switch statements (which have a different representation
from classic switch statements in the CFE) as well as switch
expressions.
We also turn on the fallback exhaustiveness algorithm by default.
Unit tests can still disable it by temporarily setting the global
variable `useFallbackExhaustivenessAlgorithm` to `false`.
The hope is that this algorithm will be short-lived; we are just using
it so that if we decide to enable pattern support in the near future,
users will experience something that is sound. That is, it may
require `default` or `_` cases more often than is strictly necessary,

According to the language specification:
1) When 'break' is executed in the 'await for' loop (in 'main'),
the underlying stream subscription is canceled.
2) When async* function ('consume') has stopped at 'yield' or 'yield*',
and the stream is canceled, the 'yield' / 'yield*' statement returns
without an object. It also means that code in 'consume()' after
the loop is not executed and it doesn't append ")" to the log.
So the test expectations are fixed to avoid expecting trailing ")"
at the log when there is a 'break' out of the 'await for' loop.

Avoid quadratic behavior when multiple chunks fail to
have a line break, and the carry-over string gets repeatedly extended.
In the original chunked conversion code, the chunk handling code retained the trailing, non-line-terminated text of the previous chunk, then eagerly concatenated it with the next chunk in order to continue looking for lines. That's moderately effective when lines are shorter than chunks, and neither are too large.
However, a very long line spread across many chunks would perform repeated string concatenation with quadratic time complexity.
This change gives `LineSplitter` the option of using a `StringBuffer` to collect multiple carry-over line parts.
The buffer is needed whenever a chunk does not contain a line break, and needs to be combined with a previous chunk's carry-over. This avoids ever directly concatenating any more than two strings.
The `StringBuffer` is not allocated until it's first needed, so if lines are generally shorter than chunks, the buffer won't be used. Once allocated, the buffer is retained in case a buffer will be needed again, but cleared when its contents are used.
The code optimizes for the simple case of each chunk having a line break.

Before we can reify `JSUndefined` and `JSNull` we need to give users a way to detect these values. Once existing users have migrated to these new helpers, then we can start boxing `JSUndefined` and `JSNull` on Dart2Wasm.
There are a few steps here:
1) Land these helpers, but for now they will just preserve the existing semantics.
2) Deploy JS types to Flutter and `package:test`, i.e. everywhere Dart2Wasm's JS interop is currently being used, and use these helpers instead of `null` checks.
3) Switch the semantics of the helpers to stop conflating on all Web backends, while simultaneously boxing `JSNull` and `JSUndefined` on Dart2Wasm.

This adds support for record types in the exhaustiveness algorithm.
The original algorithm was based on that record pattern would
match fields on all types, but that is no longer the case. Instead
record patterns only match corresponding to their own type. For this
reason the testing code is updated to create record spaces in relation
to a type. For instance, when the test create a record space {x: B}, it
is know create in relation to a type, say (x: A, y: A), and the create
space will therefore have (x: *, y: *) structure where the y: component
is implicitly Top, similar to how object patterns are used.
Unlike the Dart record types used for type checking and inference, the
record types used for exhaustiveness do not take the field types into
account for its subtype relation. This is avoid conclusions like
(int i, Object o) and (Object o, int i) having no values in common because
their corresponding types (int, Object) and (Object, int) are not subtypes
of each other. Instead, the subtype relation for record types used for
exhaustiveness only use the structure of the record to determine whether
two types are related.
Note though, that fields of a record type still know the type of the field.
This is used when expanded a record type into a space; the field spaces
will be derived from the field types in this case.
