7b51dc7edb Cleanup the AST code by removing unused parts and get rid of the
flow graph code completely. Add new AST node for null compares
and use it to make the full codegens better at generating code
for null comparisons.

04a5802d80 Add iterative primitive type analysis.
This change adds a data-flow pass to statically determine
if a variable contains a primitive type.

It requires building the flow graph and computing reaching
definitions as pre-requisites. The analysis annotates all
VariableProxy nodes with the result.

88f6734ddb Add a pass for the fast compiler to label expression nodes.
This change adds a post-order numbering to AST nodes that
are relevant for the fast code generator. It is only invoked
together with the fast compiler. 

Also changed the ast printer to print the  numbering for 
testing purposes if it is present.

a563800b4c Initial implementation of printing the AST as a JSON string. This
implementation is not yet complete (it prints only the node name for
some AST constructs) and does not serialize everything needed to
reconstitute the AST.

It is motivated by a desire to prototype source-to-source
transformations in JavaScript itself (or anything else that can grok
JSON), but it should have other uses too.

Feedback is welcome.

a48fd5916e Change the overly-general class named Node to the more specific
AstNode in case we ever want to have some other kind of node.

Split the NODE_LIST macro-generating macro so that we can iterate
concrete subclasses of Statement and concrete subclasses of Expression
separately.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide.
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

35939fd987 Track whether a node or variable are likely to be a Smi value. Propagate that
knowledge in the AST and inline the Smi check into the generated code if it
is deemed high value (e.g. in loops).
