Alexander Markov 53497549ab [vm] Specialize 'new List()' on kernel AST 
In VM, 'new List' is equivalent to either 'new _GrowableList' or
'new _List' depending on the number of arguments.
This change does the transformation early (on kernel AST), in order
to have specialized representation in TFA and in bytecode.

Alexander Aprelev c688d0c0c3 [frontend] When serializing compiled expression proc, clone type params first. 
If there are circular references between type parameters and types in the bounds,
currently serialization leaves original type parameters unchanged, which results
in failures to serialize compiled expression procedure.

This CL makes sure to clone all type parameters first, then passes map
with old-to-new type parameters to CloneVisitor.

Daniel Hillerström de984e58cb Type checking for redirecting factories. 
Implements static semantics for redirecting factories (c.f. §10.6.2 of
the specification). This CL does not include inference of actual type
arguments on redirectees, that is it does not handle the case where
type arguments have been omitted on the redirectee as in this
following example program:

  class A<T> {
    factory A() = B;
  }
  class B<T> implements A<T> {
    B();
  }

Closes https://github.com/dart-lang/sdk/issues/32988.

Also resolves the second part of
https://github.com/dart-lang/sdk/issues/30579.

Can possibly also close https://github.com/dart-lang/sdk/issues/11578.

Vyacheslav Egorov 348ed30efd [vm/kernel] In async transformation check if strongMode is on. 
It seems we are still using non-strong mode targets in few
places (e.g. when training front-end server we by accident
train it in legacy mode).

A separate bug is filed to clean that up https://github.com/dart-lang/sdk/issues/34468

For now to unbreak the build we simply check if we are in the
legacy mode and then avoid using getStaticType in async
transformation.

This is followup to eec96f9076.

Vyacheslav Egorov eec96f9076 [vm/kernel] Preserve strong mode types in async transformation 
Async transformation uses dynamic variables in few places (e.g.
for temporaries and for incomming arguments) - which creates
not strongly typed AST with method invocations having dynamic
receivers and non-null interface targets at the same time.

To maintain strong typedness of the AST we insert unsafeCast
when accessing the temporaries.

Peter von der Ahé 00ceb8e359 Share type handling between BodyBuilder and OutlineBuilder. 
The BodyBuilder now operates on TypeBuilders instead of DartType.

This

* enables better error messages, and

* paves the way for removing the dependency on OutlineBuilder from BodyBuilder.

danrubel c7960df357 Generate analyzer error codes from messages.yaml 
With this change, analyzer error codes can be generated from messages.yaml
and those error codes easily translated from the corresponding fasta error.

Each fasta error code in messages.yaml that has an "index:" field
(see prior CL https://dart-review.googlesource.com/c/sdk/+/74040)
now has an Analyzer error code automatically generated
with the information in messages.yaml. In addition
a list of all indexed errors is generated so that a fasta error
code can be quickly translated into an Analyzer error code.

Jenny Messerly 24493c2f54 Add support for dartdevk to read Analyzer summaries into Kernel format 
This allows dartdevk to be used in the context of an existing build
system based on Analyzer summary files. This will ease migration of
existing dartdevc users over to dartdevk.

Kevin Millikin cbfc78f5b2 Parse mixin declarations as if they were classes 
In Fasta's outline builder, parse mixin declarations as if they were
the corresponding class declaration:

mixin M<T0,...,Ti> on S0,S1,...,Sj implement I0,...,Ik {...}

is parsed as if it were:

class M<T0,...,Ti> extends S0 with S1,...,Sj implements I0,...,Ik {
  ...
}

This supports the syntax and should automatically provide an
implementation of the runtime semantics on the VM.  Not all of the
required static checks are implemented in the front end.
