818c4b5bfd Remove AbsolutePathContext and use package:path instead.
I see however that linter/test/rule_test.dart uses it, but as far as I
can see, that's it. All other usages are from analyzer and
analysis_server.

Simple cases where the type has no type parameters are handled.

The next step is to introduce a signature-like j-model entity to compute the type in more complex cases.

bd757f9948 Redo #28580: instantiate bounds to bounds.
One thing to be careful of here is that function type bounds may be
left unbounded. However, their parameters and return type cannot refer
to a type parameter for resolve-to-bounds to work.

There are also a large number of ways that this can loop infinitely, and
a number of new guards had to be added (as well as some test cases) to
catch them all.

10b441b16b Improve conditional import expression recovery
This improves recovery when parsing conditional import expressions
by repositioning the synthetic closing ')' that was inserted by the
scanner in a less than optimal location.

This approach relies on the beforeSynthetic field being set correctly.
While the scanner still sets the 'next' and 'beforeSynthetic' fields
directly for efficiency, most other functions which update an existing
token stream have been revised to call 'setNext()' rather than setting
the 'next' field directly. This ensures that the 'beforeSynthetic' field
will be correctly updated.

4fdf84e4f4 # Enter a description of the change.
Make all lists returned by ast_from_binary growable so the ast is more consistent with the ast generated by parsing dart code which generally contains growable lists as opposed to fixed-length lists.

This fixes a bug in the Flutter --track-widget-creation transform
where it would fail on an AST if it was deserialized from a binary file
rather than parsed from source code.

3b057dea98 [VM] Remove legacy Object::empty_context() and CTX constant
Our generated code does not keep the context in a special register
anymore (for quite some time now).  The context is just another definition
in the IR language and gets assigned register locations by the linearscan
register allocator.

Furthermore we no longer use an empty context for closures which have no
captured states, instead the context of those closures is just `null`.

This CL therefore removes Object::empty_context() and the CTX constant.
