This CL adds a test for what was fixed in
79cc54e519, namely that when loading a
concatenated component, the uriToSource map shouldn't have its values
overwritten with objects with no source in them.

The Kernel package has its own internal tests for substitution on
DartTypes. This CL updates the parser for the types in the tests, so
that the nullability attributes are recognized and used.

Before a import of, say "hello.dart" was printed as
"import './hello.dart'".
Now instead it is printed as "import 'hello.dart'".
At the same time we get rid of a dependency.

Fasta can generate synthetic libraries.
Previously we didn't include them when serializing, but that leaves
references in the binary to libraries that doesn't exist which isn't
ideal.
This change includes them, and adds a flag to kernel Libraries such that
we know they are synthetic.

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.

The length is redundant if the list is delimited. Serializing the
length had the slight advantage of preallocating a list of the correct
size and the disadvantages of being harder to maintain by hand and
ugly to read.
Instead, delimit lists. The empty list is naturally ().

Serializing Let requires us to serialize variable declarations which are
complicated. They require us to support optional values because they
have an optional initializer. This is done by using a _ for none.
Having support for Let will allow us to support variable get and set.

Use the operator string as the tag. This requires us to be able to
serialize a sequence of (two) things. Homogeneous lists don't give us
static typing so we introduce a pair class.
This requires allocating a pair (serializing a list would require
allocating a list anyway). When we start generating and optimizing
the combinator applications we expect to eliminate the pair allocation
overhead.

Begin serializing expressions. Fairly quickly you encounter the cyclic
dependency between class Expression and any subclass that contains
nested expressions. It isn't possible to implement this with immutable
values in Dart.
A quick solution is to break the cycle somewhere. Here, the cycle is
broken by late initialization of the serializer for Expression.
Serializers are still immutable (either const or with all final fields)
and still singleton instances (by virtue of being static fields).

Use json.encode/json.decode. This gets some strings wrong but it
should be enough to make more progress.
Testing with hardcoded strings is already getting awkward.
