+ emit only one message per method given that it now always has the
same root cause, namely that the combined member signature does not

Lasse Reichstein Holst Nielsen b64550eaff Add a nullFuture in dart:internal.
This is the future returned by `dart:async` in some cases which used to return `null` pre null-safety.
Code inside the SDK which *needs* to not change its timing of events can recognize the future and skip waiting for it, giving the same "synchronous" behavior as before the null safety change.

Longer term, we need to wean people off depending on the specific interleaving of events.
Maybe we should randomly shuffle our microtask queue.

Aske Simon Christensen b11d057572 [vm] Look for the recognized pragma in the unboxer and signature shaker.
This removes the conservative exclusion of everything below num in the
unboxer, and it allows some methods marked as entry points to not be
entry points, as they are not actually referred explicitly in VM code.

Aske Simon Christensen 1ab705f60c [vm] Require all recognized methods to be marked with pragma.
Adds a @pragma("vm:recognized", <kind>) to all recognized methods, where
<kind> is one of "intrinsic", "graph" or "other", corresponding to the
kind of recognized method.

When running in debug mode, it is checked that all recognized methods
are marked with the correct kind of pragma, and that all methods marked
with the pragma are in fact recognized.

This enables kernel-level analyses and optimizations to query whether
a method is recognized by the VM.

TEST=Asserts that check the correspondence both ways, covered by test
suite, in particular the various CompileAll tests that compile all code.

Clement Skau 7f0bd5e811 [VM] Removes _Future's and _StreamImpl's _awaiter.
Changes debugger.cc to use the 'lazy async stack' mechanism for
unwinding async stacks, which means we no longer have to manually
keep track of the caller.

This also allows us to get rid of _asyncStarListenHelper.

Johnni Winther db98b69aea [cfe] Handle duplicate late fields
Flow analysis was failing on our encoding of duplicate late variables.
We add an invalid expression as the initializer on duplicate variables
and flow analysis was seeing this as if the late variable had (declared)
initializer. Changed to use the `hasDeclaredInitializer` flag on
VariableDeclarationImpl to bypass flow analysis in the synthesized
initializer.

Original change's description:
> Flow analysis: promote to non-nullable on initialization
>
> When flow analysis encounters a variable declaration of the form `T? x
> = expr;`, if the type of `expr` is `T`, then the variable is
> immediately promoted to type `T`.
>
> Fixes #43099.

Johnni Winther 749b622a6b [cfe] Don't override language version of opt-out libraries in strong mode
This change compiles opt-out libraries with opt-out semantics even when
sound null safety was requested. The compile-time error that libraries
cannot opt out with sound null safety is still produces but spurious errors
from interpreting opt-out as opt-in are avoided.

This also aligns the compilation of from-source with from-dill for the
case of opt-out libraries in face of sound null safety.

Closes #43327
