Reaching definitions in (RD_in) is initially empty for all nodes. Gen

Also: two small changes to flow graph printing. Children of branch
nodes are visited in right-to-left order when performing depth first
search. Instructions are numbered locally within blocks so as to not
destroy AST node number before printing (it's useful to print the
definition).

Add an assigned variables analysis.
...
This change adds a pass over the AST that computes the
set of assigned variables for locals and parameters for each expression.
The result of this analysis is used to for two purposes:
1. Recognize variables that are trivial subexpressions. A left sub-expression
of a binary operation is trivial if it is a local variable or a parameter
and it is not assigned in the right sub-expression. In the case of a
trivial left sub-expression we evaluate the right first.
Currently only binary operations and compare operations are considered
when finding trivial left sub-expressions.
2. Recogize certain simple for-loops with a constant trip count where the loop
variable is always within smi range. If the loop count variable is not
assigned in the body of the loop (except in the update expression the
for-loop). This allows omitting smi checks on operation using the loop
count variable.

Add defensive checks to the flow graph builder.
...
Visitor stack overflow is used to signal an unsupported construct in
the flow graph. Check for it in more places. Make the utility
functions for appending to graphs handle more cases if they can be
handled correctly.
Remove the entry node in favor of a block with a NULL predecessor as
single entry. Represent the empty flow graph as a single empty block.
Add empty blocks lazily where needed to preserve edge-split form.
