Kevin Millikin 6ac6baae8e Record interfaceTargets for calls on dynamic receivers
When calling Object methods on dynamic receivers, record the
interfaceTarget it Kernel.  Back ends will use this to treat the call
as a statically typed one.  This is half of the problem in

Kevin Millikin b62b438e8a Infer Object members for dynamic receivers
For method, getter, and setter invocations with names of methods on
Object on expressions with static type `dynamic`, if the invocation
cannot possibly be an invocation of noSuchMethod, infer the type of
the invocation using the type of the member of Object.

Alexander Aprelev e71bd048e5 [vm, kernel] Fix async stack code traversal in dart2.
With this change debugger requests yield(await) positions from kernel builder so it can confirm which frame handles what exceptions.
This also renames ':completer' to ':async_completer' in constructed kernel, so it is compliant with what VM expects to see(and updates test expectations accordingly).
Further it fixes async stack navigation for sync-async that became default in dart vm since first version went for the review((uses `future` getter, rather than property).
It also makes `future` getter non-debuggable to allow stepping-out of async methods.

Make Handle zone-scoped. Clean up frame counter var name.

Samir Jindel 1a23ff68a5 Fix incorrect handling of NSM forwarders and pull all logic into CFE. (Take 2)
The behavioral difference is that named and optional arguments are filled in
with their default values in the `Invocation` object passed to `noSuchMethod`.

On the implementation side we make NSM forwarders concrete and fill in their
bodies in the CFE. The custom (and somewhat hacky) VM support is no longer
needed, and Dart2JS can benefit from this implementation as well.

According to discussion on #33031 we will be able to re-land this soon without
breaking Mockito.

Prior failures on precompiler bots are fixed in Patchset 2.

Paul Berry 45b02f8216 Use the new spec for Future flattening for type inference
Change Fasta type inference and Kernel type checking to use the new
definition for Future flattening, which is really unwrapping (peeling
off one layer of Future or FutureOr).  Use this for inferring types of
`await` expressions and return types from `async` functions.

Ensure that we are using the same notion of flattening for inference
and checking.  (Maybe it was a red flag that we weren't.)

This fixes await_test so that it produces a runtime error rather than
a compile time error - see #31541.

A similar change will need to be made to the analyzer - see #31887.

Aske Simon Christensen 0c03458717 Reland "Treat most warnings as errors in strong mode."
Reland of https://dart-review.googlesource.com/c/sdk/+/29160

Adds a 'severity' field to diagnostic messages and replaces all
addWarning and addNit functions by a generic addProblem, which uses
the intrinsic severity of the message. Eventually, errors should
also be reported this way.

A special severity value maps into either warning or error for Dart 1
and Dart 2, respectively. Most Dart 1 warnings are in this category.

Fixes some 320 failures of DDK test expecting a compile-time error.
These were previously masked by a workaround in the DDC error handler
which has now been removed.

Closes https://github.com/dart-lang/sdk/issues/31286

Kevin Millikin 6fa813d818 Change handling of Kernel static errors
Before: Kernel static errors were represented by throwing a distinguished
error or else by calling a distinguished library const constructor.

Now: Kernel static errors are represented by InvalidExpression.  To support
error reporting, InvalidExpression has an optional message and a file
offset.  A back end can choose to signal these errors at any time; for
example, when deserializing the binary, or when compiling the procedure
containing the static error, or when the erroneous expression is evaluated
at run time.

InvalidStatement is removed because it can be encoded as ExpressionStatement
of InvalidExpression.

Future work:

* supporting static errors where an expression cannot appear in the AST
* allowing InvalidExpression to contain an Expression for error recovery
* adding a top-level list of static errors and warnings to the binary
