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 adds a Node.toText method together with an AstPrinter. These
facility and better toString implementation on AST nodes while allowing
for toString independent printing of AST to use in testing. This also
add support for an integrated toString of custom/internal nodes.
Some work is still needed in bringing the toString implementation on
all nodes to the old quality, and not all internal nodes have
customized textual representations yet. This work is left for future
CLs.

AOT transformations add vm.direct-call.metadata with devirtualization
information to AST nodes.
Bytecode generator should take this information into account when
generating bytecode in case of AOT. Bytecode format is extended with
CheckReceiverForNull and UncheckedDirectCall instructions, and
DirectCallViaDynamicForwarder constant pool entry in order to represent
devirtualized calls.

Before this change we allowed to serialize some references as null,
and would only complain when trying to read the dill back in.
This CL changes that so it complains up front.
It is unknown if any of this would ever occur in practise.

Metadata is no longer written ahead of all nodes. Instead, metadata for
each node is written in the same context as the node itself (into a separate
buffer). This allows metadata to contain (serialize) arbitrary nodes
(for example, arbitrary DartTypes) and use serialization context of parent
nodes (such as declared type parameters).
However, with this change metadata looses the ability to reference
arbitrary AST nodes. This ability was overly restricted and had no
practical uses. (It was not possible to reference nodes which are not
reachable from root Component. As a consequence, it was not possible to
write references to arbitrary DartTypes.)
This change aligns the serialization capabilities of metadata with
how kernel AST nodes are serialized.

* The package:kernel/transformations/precompiler.dart is moved to
package:vm and split into 2 libraries: metadata/direct_call and
transformations/cha_devrtualization.
* Fasta 'target-options' command line argument and
package:kernel/target/implementation_option.dart are cleaned up
as they are no longer used.
