Implicit setters of covariant fields (both covariant by declaration and
covariant by class aka generic-covariant-impl) need to perform a type
check of their argument.
It means that inferred type of the field cannot be used as inferred
type of parameter of such setter. This change removes such uses of
an inferred type of the field, which restores parameter type check
which was previously incorrectly optimized out.

Initializers of late local variables are wrapped into closures.
The result type of a closure is a static type of the variable.
So initializer of a late variable with static type Never have a call
to a closure with static result type Never.
TFA summary collector handles calls with static result type Never
specially, treating all subsequent code as unreachable (by setting
control-dependent condition to empty). As a result, all subsequent
code after late variable with static type Never (and initializer) is
tree-shaken.
The fix is to avoid propagating control-dependent condition out of
the late variable initializers.

This adds a VariableDeclaration node which is used in ForStatement instead of VariableStatement.
This is a step towards removing the initializer from Variable. Long term, VariableDeclaration will own the initializer expression for variables and function parameters will have a defaultValue property instead of using the initializer property for the default value.

The standalone target used `JSStringImpl` as the name for its string
implementation even though JavaScript isn't involved in that at all.
This was to simplify parts of the compiler which can then refer to both
classes with the same name.
Changing this in the compiler is not that complicated however, so it
makes sense to align the string implementation name with the embedder
terminology we also use for other host imports.

This separates VariableDeclaration from Statement. VariableDeclaration no longer implements Statement and variable declared in a block or in a for-statement are now wrapped by a VariableStatement.
Currently there are two VariableStatement implementations; LegacyVariableStatement for variables in the current model, called LegacyVariable, and VariableInitialization for variables used in the new, still experimental, encoding that supports scope computation.
This CL is a step towards realigning the AST nodes to the new model in which each kind of variable has its own distinct subclass. (LocalVariable, PositionalParameter, NamedParameter, SyntheticVariable, etc.)
Note that it is not the intent to use VariableStatement in ForStatement going forward but that will be handled in a follow-up.

This change introduces the `dyn-module:dynamically-callable` and
`dyn-module:implicitly-dynamically-callable` entrypoint pragmas. It
changes the annotator to attach these pragmas to kernel nodes based
on the dynamic-interface and updates TFA to treat these nodes as
reachable and not elegible for tree-shaking.
On a later change, the pragma will be read by the VM to verify that
dynamic modules can only call dynamically members that were exposed

Before this CL, we were only recording constants once, in the first
loading unit that they were found. Now, we record them in all loading
units.
The different backends have different behavior, so for now this CL
special cases some of the test expectations. It would be better to
write these tests in a different way: For example reading the json
file and seeing that we find at least two different loading units.
Also, the implementation uses the fact that we're not using source
information anymore. We should consider simply removing it from the
dart2js backend.

For redirecting factories we actually have a fair bit of info,

redirections like tearoffs, we can actually record them like direct

To cover the feature set of the Flutter Icon Tree Shaker, we must be
aware of all non-const ways an object of a type can be created for
which we are recording the const instances.
(For more info see https://github.com/flutter/flutter/issues/181342.)
So, record all constructor invocations, and all constructor tearoffs.
The VM preserves high-level Kernel AST nodes, requiring minimal
changes:
* Direct handling for ConstructorInvocation and ConstructorTearOff.
* `isBeingRecorded` to recognize unannotated constructors.
WASM enables more CFE lowerings, requiring more unmangling:
* The CFE replaces ConstructorTearOff with a
StaticTearOff to a synthesized wrapper (e.g., _#Class#new#tearOff).
* Logic to skip the bodies of tearoff lowerings.
* Expanded ConstantCollector to handle StaticTearOffConstant and
RedirectingFactoryTearOffConstant, which are used in WASM's lowered
constant pools.
* Updated `isBeingRecorded` to map synthesized procedure names back
to their original constructors to determine if they should be
tracked.
The dart2js backend is fairly straightforward.

reports them as instances.

* Correctly report `NonConstant`s only for non-constants and
`UnsupportedConstant`s for unsupported constants.
* Added support for partial constants in `List`s, `Map`s, and
instances.
* Added error messages that report unsupported constants in terms
of the Dart language rather than compiler internals where
possible..

Record only for definitions in libraries with a `package:` uri.
* Converts all the tests to be in packages.
* Bonus: This removes the uri-mapping in equality checks.
* These packages are added to the root pub workspace.
* For the dart2js tests we need to do some juggling to keep the
tests files in memory.
* Only support `package:` uris
* Removed all the `relativizeUri` code for file paths.
* Start emitting errors on non `package:` uris with a `@RecordUse()`
annotation.
Unrelated cleanups:
* We no longer support recording const instances in annotations, this
PR cleans up code in `kernel` and `type_flow`.

Currently tree shaking of fields is disabled if there's constant
instances, due to risk of breaking constant identity.
Though identity isn't affected if all constants have the same value for
the field.
An example where we benefit from tree shaking such fields is protobuf:
In the `package:protobuf` `ProtobufEnum` class there's a field for the
string representation of the enum.
But users can compile via `-Dprotobuf.omit_enum_names=true` which makes
this field always be the empty string and effectively unused. That in
return can make thousands of such constants have one less field.

Stop recording annotations (in the VM and dart2wasm).
The visitor will stop visiting as soon as it is in an expression that
is in the annotations list.
The tests have been migrated so that their constants occur in the executable code instead of annotations.
One test has been kept to see that the annotations no longer are
recorded:
TEST=pkg/vm/testcases/transformations/record_use/instance_method.dart
A new test has been added to ensure we're also recording constants
nested inside other constants.

This record_use package will now be shared by the VM, dart2js and
dart2wasm. It's used for internal dart2js apps today to tree-shake i18n
information.
Here we use the VM's transformer to gather the usage data but introduce
a new mechanism for getting load IDs since dart2wasm doesn't use the
VM's load ID infrastructure.
