Konstantin Shcheglov 615928c514 Stop referencing non-API TypeSystem in analyzer. 
Replace it with TypeSystem from lib/dart/element/type_system.dart,
or (internally) with TypeSystemImpl.

We keep the old TypeSystem where its is exposed from API:
- ResolveResult.typeSystem
- AnalysisSession.typeSystem
- AnalysisContext.typeSystem

  We will make changes to these as a breaking change later.

Paul Berry 12265c4e42 Hacky prototype of how to fix the seventh item from #39247 
The issue is:

  lib/src/logger.html, line 107, inserted !:

  In this case the single reason detail reads "node with no info (type(2171))" with no destination.

The problem is that InstrumentationInformation.nodeInfoFor is only
considering a limited set of possible sources of nullability nodes
(the primary nodes of decorated types passed to the instrumentation
listener methods `implicitReturnType`, `implicitType`, and
`implicitTypeArguments`).  It needs to also consider decorated types
passed to `explicitTypeNullability`, `externalDecoratedType`, and
`externalDecoratedTypeParameterBound`, and it needs to walk these
decorated types recursively to discover all the nodes they point to.

Additionally, the logic in InstrumentationInformation.nodeInfoFor is
inefficient; it walks through all the implicit types in every source
file, which means that it is O(N) in the size of the code being
migrated.  Since it is called O(N) times, this is an overall runtime
complexity of O(N^2).

I've prototyped a possible fix using an expando to compute
NodeInformation for each node once at the time it's reported to
instrumentation.  This is incomplete and intended as a starting point
for discussion.  Work that still needs to be done:

- We don't produce a sensible description string for nullability nodes
  associated with AST nodes, so we present unhelpful text to the user
  like "A nullable value can't be used as the explicit type ???"; it
  would be nicer to say something like "A nullable value can't be used
  as positional argument 0 of Level.>=".  We may want to consider
  modifying the instrumentation API to make it easier to generate a
  useful string here.

- I haven't verified that the description string we produce for
  external decorated types is helpful.

- I haven't verified that the we produce a useful link for external
  decorated types.

- We should probably get rid of the data structure
  NodeInformation.explicitTypeNullability (which has similar
  inefficiencies) and change over code that was using it to use the
  new approach.

Paul Berry 7e8e66016a Migration: do not use always or never in already-migrated types. 
Previously, when the code being migrated referred to a nullable or a
non-nullable type in an already-migrated library, we would use the
`always` or `never` graph node to represent the nullability of the
type.  This was problematic, because it made it difficult for
instrumentation to pinpoint precisely which element in an
already-migrated library was the cause of an expresion being
null-checked, or a type being made non-nullable.

We now create a fresh nullability node for each non-nullable type
coming from already-migrated code, with an edge to `always` or `never`
to ensure that the fresh node has the correct nullability, so that
instrumentation can see precisely which element it came from.

Since the migration tool doesn't traverse the ASTs of already-migrated
code, we can't report an AST node that caused such an edge, so an
`element` getter has been added EdgeOriginInfo to allow us to report
the element that caused the edge.

As before, types associated with already-migrated code are reported to
instrumentation via InstrumentationListener.externalDecoratedType.  As
a new enhancement, bounds of generic parameters in already-migrated
code are reported to instrumentation via
InstrumentationListener.externalDecoratedTypeParameterBound.

Also multiplex the service rather than the logger, so that we can

Ari Aye 5bae0f23cf Increase completion model token lookback to 100 
In moving to a pointer mixture network from a traditional language
model I had initially decreased model lookback to 50 tokens to
facilitate faster model training iteration. Now that we've landed
on a configuration that works well, increasing lookback to 100 tokens
improves accuracy further.

I also went ahead and followed a recommendation from Jacob to
oversample Flutter sources since they're greatly underrrepresented
in our training corpus compared to our users' code at prediction time.
