- Introduces a new output subdirectory `gen/utils/ddc` where the
new build targets output files. This is intended to make the
migration to the new assets easier since landing this change
shouldn't immediately break any dependencies.
- Enables building the canary and stable assets at the same time.
- Changes more names in our workflow from "dartdevc" to "ddc".
- Updates the ddc-canary-linux-chrome and
ddc-canary-linux-chrome-unsound configurations to use the
new assets.
The new outputs appear in directories that are more consistently
named, (no more sound vs kernel confusion). They are named in
preparation for the eventual deletion of the unsound targets
without any lingering cruft to be cleaned up in the sound
directories.
The new structure is:
```
gen/utils/ddc/
|- canary
| |- pkg
| |- sdk
|- canary_unsound
| |- pkg
| |- sdk
|- stable
| |- pkg
| |- sdk
|- stable-unsound
|- pkg
|- sdk
```
The 'pkg' and 'sdk' directories all contain outputs with the same
files names, each compiled in the respective build modes
(sound/unsound and stable/canary).

Following the refactoring we started in previous CLs, this splits string
and int patch files into (1) patch files that only patch and don't add
implementation classes (2) files for implementation classes (3) helpers.
Changes:
- `string_patch` is split into `string.dart` and `string_patch.dart`.
- VM's `integers_patch.dart` copied as `int_patch.dart` and updated.
This was needed as `integers_patch` requires VM's library paths in
imports.
We needed to copy this file to be able to optimize based on
dart2wasm's implementation classes. However in this CL we copy the
file as-is and update import paths.
- VM's `string_buffer_patch.dart` copied to be able to use the string
implementation classes from the new library.
`string_buffer_create.dart` is merged ino `string_buffer_patch.dart`.
- `getHash` and `setHash` to set object identity moved to
`object_helper.dart`, to be able to use in string implementations.
- Redundant `new` keywords in copied files removed.
One TODO added in `string_buffer_patch.dart` when allocating a new
string to the buffer:
// _parts = _GrowableList.withCapacity(10)..add(str);
// TODO(omersa): Uncomment the line above after moving list
// implementations to a library.
_parts = [str];
We can enable the old code again after moving list implementations to a
library.

When using the "mini-ast" pseudo-language to write unit tests for the
flow analysis and type analysis logic in the `_fe_analyzer_shared`
package, it is no longer necessary to use `.expr` to turn a `Var` into
an `Expression`; this now happens automatically. The way this works
under the hood is that the `Var` and `Expression` classes implement
the `ProtoExpression` interface; constructs that expect expressions
are declared with input parameters of type `ProtoExpression`, and they
automatically convert to `Expression`s when necessary.

It really looks like `_SubstitutedTypeParameters` factory
constructor assumes its `substitution` argument doesn't
include any of `elements` neither as a key, nor anywhere
it the result types. Since if it does contains a key from
`elements` that part of `substitution` will be lost, overriden by
`...substitution2.map` part of `Substitution.fromMap` call.
And if it has `elements` mentioned anywhere in values of the
`substitution` map, those won't be renamed.
But sometimes `_SubstitutedTypeParameters._SubstitutedTypeParameters`
is called with a `subtitution` that includes some of `elements`.
For example, that's what happens in both added tests.
I assume it never breaks, because the part of `substitution`
that acts on `elements` is trivial: just renaming a type
variable to a fresh name. And since `_SubstitutedTypeParameters`
just gets yet another fresh name for it, that works.
One small problem arises though if a type variable renamed by
`substitution` has a bound that references the type variable itself
(like `T extends Foo<T>`). In that case bound gets substituted with the
`substitution` first, so `substitution2` doesn't work on it anymore.
So we end up with an element `T0 extends Foo<T1>`, where `T0` and
`T1` and two different fresh names for `T`.
This commit changes the order of substitutions when handling bounds,
such that the part of `substitution` that substitutes `elements` is
effectively ignored. That agrees with the existing behavior of
rewriting this part of `substitution` in the result, so it shouldn't
make things worse.

This marks all types without subtypes as final and all types with

V8 currently ignores the finality of types for the temporary WasmGC
encoding, which make our current encoding work even though it
implicitly marks some types as final that shouldn't be. For the final
WasmGC instruction encoding, V8 is likely to reject modules containing

Previously, when using the "mini-ast" pseudo-language to write unit
tests for the flow analysis and type analysis logic in the
`_fe_analyzer_shared` package, it was possible to call `.pattern` on
any arbitrary expression, creating a constant pattern containing the
expression. This didn't make sense--only constant expressions can be
used as the basis for constant patterns.
With this change, `.pattern` is only available on the various forms of
constant expressions supported by the "mini-ast" pseudo-language
(currently: integer literals, the `null` literal, and placeholder
expressions created using the `expr` function).

In several flow analysis tests we need to model an expression with two
subexpressions, where the type of the overall expression is the same
as the type of the second subexpression.
Previously we did this using `ProtoStatement.thenExpr`, which created
a magic compound expression consisting of an expression (or statement)
followed by a second expression. This was too general, since it
allowed modelling code that would not be possible in Dart.
This CL replaces uses of `ProtoStatement.thenExpr` with a function
`second`, which models a Dart function defined this way:
T second(dynamic x, T y) => y;
This has two advantages:
- The tests are now modelling code that could actually exist in the
real world, rather than modelling pseudo-expressions that are not
actually possible to write in Dart.
- It prepares for a follow-up CL in which I'll be unifying the
representation of patterns and expressions in the flow analysis
tests; eliminating `ProtoStatement.thenExpr` will prevent a conflict
between it and `PossiblyGuardedPattern.thenExpr`.
With this change, two tests had to be deleted, because the conditions
they were testing could no longer be expressed:
- `for_conditionBegin() handles not-yet-seen variables`
- `whileStatement_conditionBegin() handles not-yet-seen variables`
This is ok, because these tests were designed to verify correct
behavior in the circumstance where the client forgets to declare a
variable. This circumstance no longer arises, because the
`_FlowAnalysisImpl` constructor detects undeclared variables and
generates synthetic declarations for them.

This allows them to be used either where an expression is exprected or
