Paul Berry b1e28691d1 Only create hard edges for local variable/parameter references.
Exception: also create hard edges for the relation between a type
argument and the corresponding type parameter bound, because that
can't be fixed by a null check.

Paul Berry e31af09992 Remove NullabilityMigrationAssumptions class.
This was a lot of bookkeeping for very little added value.  If we want
to experiment with changing the behavior of the migration tool in the
future, we should experimentally change it and see whether the quality
of the migration improves; it's not worth speculatively keeping
multiple behaviors around while the tool is being developed.

Paul Berry 709df79404 Clean up logic to decide whether to create hard edges
Previously we were creating hard edges for the default values of
optional parameters.  This was incorrect; we don't want a hard edge
because we don't want evidence of non-nullability to propagate
upstream from an optional parameter to the const expression that sets
its default value.

Paul Berry 01694dcca1 Handle nullability nodes for dynamic types more cleanly.
Rather than use an edge from `always` to ensure that these nodes are
nullable (which is error prone since it could be overridden by an
assertion), we simply place these nodes in the ordinary nullable state
at the time they are created.

As a side effect we can reduce the amount of code we have to plumb the
nullability graph through.

Konstantin Shcheglov 4979a51a9c Add information about existing imports to completion response.
This adds quite a lot of information though, because we send many
strings.

Before: 20686 characters.
After:  55345 characters.

Theoretically we could do better, and send information about existing
imports only once as well, so when the user continues typing in a
single file, without touching imports, we don't send any new data
about imports (maybe just a confirmation that it is still the same).
But I'm not sure if this is a worthwhile optimization.

Actually, even included suggestion sets have similar property - they
don't change for a given file, unless there are changes to other
libraries which we might want to include.

Paul Berry f440f77dd3 Store the nullability graph in the nullability nodes rather than in maps.
This should improve performance by avoiding map lookups.

Paul Berry 3ecb89ba8c Move NullabilityGraph into nullability_node.dart.
This will allow NullabilityGraph and NullabilityNode to have shared
access to private data without having to expose it to all other
libraries.

Paul Berry 6080e546c9 Rearrange NullabilityNode class hierarchy.
Instead of making immutable nullability nodes derive from mutable ones
(forcing the mutation method to be overridden to thrown an exception),
we make sibling classes for mutable and immutable nodes.  This will
allow additional mutation methods to be added in a less kludgy way.

Paul Berry bed74d6e97 Remove NullabilityGraph._upstream.
Its only purpose was to make NullabilityGraph.getUpstreamNodes fast to
compute, but that function was only used in unit tests anyway so there
was no need for it to be fast.  (Minor exception: it was also used in
an assert statement, but I was able to change that to
Nullabilitygraph.getUnconditionalUpstreamNodes).
