The web compilers don't support getter/field invocation encoded as a
FunctionInvocation on an InstanceGet because it doesn't work for
getter/field invocation of js-interop properties, since the InstanceGet
wouldn't result in a Dart function but just JavaScript function.
To support this in the new method invocation encoding, a special
expression, InstanceGetterInvocation, is used to encode getter/field
invocations in dart2js and ddc.

The CL is a step towards have a more restricted and wellstructured
handled of references and canonical names.
The CL moves Reference to canonical_name.dart and makes
CanonicalName.reference private, and replaces CanonicalName.getReference
with a 'reference' getter.
It also removes NamedNode.canonicalName, Field.getterCanonicalName and
Field.setterCanonicalName so that these can only be accessed through the
corresponding reference. This is to reduce the reliance on the
canonical names which, ideally, should only be part of serialization and
deserialization.

This CL completes the migration of the first wave of
interdependent libraries in package:kernel, including ast.dart.
In order to ensure non-nullability on AST properties, the Transformer
has been split in 2 variants: Transformer which doesn't support
removal of nodes and RemovingTransformer which supports removal where
allowed by the context using 'removal sentinels'.
Start reviewing Transformer and RemovingTransformer in visitors.dart
since many of the changes are caused by the changes here.
Included in the migration are the mixin_deduplication.dart and
unreachable_code_elimination.dart since these needed porting to
the RemovingTransformer which was aided by opting in the libraries
which only depended on ast.dart.

This ensure that we don't create setter references for fields that

This CL adds stub for each concrete mixed in member into mixin
applications. The body of the stub calls the original member via
a super call.
This addition means that resolution of super access now use the
stub and not the original declaration as the target, which means
that it will be correct even when mixed in members are cloned. For
this reason, dart2js no longer needs to perform its own super
member resolution.
When a super call targets a mixin super stub (after cloning) it
can be optimized away by redirecting the call to the `stubTarget`
of the call. This optimization is performed in dart2js.
Since dart2js now uses the correct super target, its runtime
mixin application needs to avoid overriding members already
declared in the mixin application. These members are the
forwarding super stubs which ensure that correct runtime types
when members with covariant parameters are implemented.

Tests are now run over entire libraries instead of their sub-trees
that are deemed to be ready for the serialization by the verifier.
The update revealed two scoping bugs. This CL fixes them as well,
namely the following:
* Result expression of a block expression should be in the scope of
the block. That is, the variables declared in the block are
visible in the result expression.
* Local function declarations should be visible in the blocks they
are declared in. Accidentally, the Bind combinator was used
instead of Rebind, resulting in local functions being visible in
their own bodies, but not in the blocks they are declared in.
