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.

Supplementary changes for handling Classes done in this CL are the
following:
* handling Supertypes
* handling Constructors
* handling remaining kinds of Procedure
* serializing AsyncMarker the same way as flags
* eliminating the need to wrap flags into IntLiteral

The flags on the fields are serialized as lists of flag names,
allowing for any combination of the flags in any order. Similar
technique is used in this CL to serialize the flags on Procedures and
VariableDeclarations. This is in the contrast with the previous
approach for those nodes, when the flags were the part of the
serialized name of the node (such as "static-method" for static
Procedures or "final" for final VariableDeclarations).

This CL adds round-trip serialization support for FunctionDeclarations
and the remining kinds of VariableDeclarations, completing the support
for statements. Additionally, the CL fixes a variable scope issue in
Catch clauses, namely that the exception and the stack trace variables
should be visible in the body.

In addition to supporting the nodes, the notion of Binder is
reworked. It doesn't store the computed local distinct name on the
node itself now, as it's not always possible (which is the case of
LabeledStatement), but keep it in a map.

The CL reduces the number of false positive cases in the round-trip
serialization unit testing by refining the verifier analysis. Not it
doesn't attempt to make the round trip over the sub-trees containing
free variables.

Add Kernel syntactic support for constants constructed by
bool.fromEnvironment, int.fromEnvironment, and String.fromEnvironment.
These values are not necessarily available at compile time. Because
constants can depend on these values, there is also an unevaluated constant
that represents an expression depending on environment values.
This syntax is not yet produced by the Fasta compiler.
