Jens Johansen 4d3d70af23 [kernel] Format kernel
Kernel sdk version was bumped from 3.6 to 3.12 in
https://dart-review.googlesource.com/c/sdk/+/487542 (and to `^3.12.0-0`
in https://dart-review.googlesource.com/c/sdk/+/487880) but the source
was never formatted.

This is, if nothing else, bad for reviews, where editing a file changes
the file in lots of places because of new formatting.

This CL is the result of running

```
out/ReleaseX64/dart-sdk/bin/dart format pkg/kernel/
```

but also updates the formatter version used by a source generator
(`pkg/front_end/tool/visitor_generator.dart`) so things agree.

Johnni Winther 988cd0f9b7 [cfe][PrimaryConstructors] Add isRedirecting/SuperInitializer flags to InvalidInitializer
This adds isRedirectingInitializer and isSuperInitializer to the Initializer hierarchy and adds flags to InvalidInitializer to signal when the InvalidInitializer should be taking as a redirecting or super initializer. This allows us to avoid miscatergorizing such declarations when they are erroneous.

Alexander Markov 99929813b0 [vm,kernel] Add unique IDs for local functions in kernel AST
The unique IDs are assigned during VM-specific lowering transformation
and recomputed during TFA tree shaking.

The IDs are not assigned when local function AST nodes are created
as it makes certain AST transformations very fragile (e.g. moving
a sub-tree to another parent, cloning a tree to insert into another
member).

The IDs will be used to identify local functions within a member by
the VM and different compilers (dart2bytecode, modular AOT).

Jens Johansen ed64348f68 [kernel] Calculate scopes for expression evaluation differently
This CL introduces an alternative way to calculate scopes for
expression evaluations. Currently the previous method is kept as well.

What this does is that it:

* Finds all nodes that match the offset and uri. (Ideally there's only
  one, but that's not always the case --- it's the case for less than
  60% of cases in the test added actually).
* Calculate the scope along the way.
* Return the scopes of all the found nodes that offset.

A test that asks for ~all file offsets in the dill files in the sdk and
compares the result with the scope the binary serialization computes is
added.
A single point can't always be found (for all dills in the sdk
only ~58.93% returns a single result), but for each query the wanted
scope is among the results returned.
For the non-outline dills in the sdk, between ~87.93% and ~94.52% of
the results are either a single result or multiple results with the
same actual scope in all of them.

Note that the test asks for ~all offsets, not just "debuggable" or
"stopable" offsets (which will likely vary depending on the vm/web
backend etc) --- likely the percentage will be higher for those points
though.

When this returns multiple results one can likely be picked by the
client based on information it has about names of variables in scope
etc.

Note that the test is rather slow, on my machine with the platforms
available there it makes 3,908,181 queries in ~3.5 minutes.
(Which corresponds to roughly 18,610 per second or under 0.06 ms per
query on average though, so it doesn't seem like a concert for actually
using it.)

Expressions missing offsets were:

* I'm not sure how TypedefTearOff is actually being used, I don't see reference to it in the VM runtime. Unless the CFE lowers it before the VM gets it.

I also added a test on `binary.md` that ensures all expressions include a file offset in their serialized format. This can be expanded to statements if offsets are added to the remaining statement nodes without offsets.

TEST=Added binary_md_git_test.dart to ensure all expressions contain offset data going forward.

This renames ExtensionType.typeErasure and adds it to DartType. This also fixes the extension type erasure for when extension types are used in the arguments of an extension type.

DartType.extensionTypeErasure can be used by backends to easily
access the type without extension types for any type.

Nate Biggs 175c949398 [cfe] Fix more cases of kernel AST serializer missing file offset.
Dart2JS uses the file offset on these nodes to create JS source maps. We want to maintain these file offsets across the serialization layer when we compile from dill files rather than directly from sources.

This last CL resolves all diffs observed in test files in pkg/compiler/test/inference/data.

TEST=Updating tests for all of these in fasta offsets tests.

Dart2JS uses the file offset on these nodes to create JS source maps. We want to maintain these file offsets across the serialization layer when we compile from dill files rather than directly from sources.

Dart2JS tests were serializing via `--test-mode` flag and thus had incorrect source locations for some stack traces.

Chloe Stefantsova de302d7f3b [cfe] Introduce StructuralParameters
This CL introduces StructuralParameter and StructuralParameterType
classes. They are intended to replace TypeParameter and
TypeParameterType respectively where those were used as type
parameters defined by FunctionTypes. Previously, type parameters of
FunctionTypes were represented by TypeParameter objects with the
‘parent’ field set to null. By introducing StructuralParameter and
StructuralParameterType this CL unambiguously separates the two
notions of type parameters.

Nate Biggs a503edf481 [cfe] Fix kernel (de-)serialization missing field offset on FieldInitializer.
We are experiencing diffs in Dart2JS source maps in `--test-mode` which does a serialization round trip. JS that should map to default parameters is instead mapping to the surrounding `Constructor` member since the FieldInitializer's offset is getting dropped.

This is affecting any Dart2JS split action build since those all end of serialiaing and deserializing the kernel. Any other tools using this serialization would also be affected.

TEST=Existing/will add in follow up.

There is an `includeSources` option today to skip writing both source bytes as well as the line starts. Dart2JS needs the line starts to generate source maps from its modified dill. But the actual bytes aren't used passed a certain point. This new option would allow us to exclude the information we don't need from the dill.

For large applications this can reduce the size of the dill by close to 50%.
