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.

Small simplification of #include dependencies.

Remove messages.h from v8.h and include it explicitly in only the few places
it is needed.  Many files relied on getting handles-inl.h implicitly from
messages.h through v8.h, so include handles-inl.h explicitly in v8.h
instead.

Remove zone-inl.h from header files where it is not needed, can be replaced
by a forward declaration, or can be replaced by zone.h (specifically,
factory.h and heap.h).  Include zone.h or zone-inl.h in header files where
it was implicitly included via heap.h or factory.h.  Prefer zone.h over
zone-inl.h in header files where possible by including zone-inl.h in .cc
files.

single (labeled) successor edge.  Branch nodes are explicit, they have a
single predecessor edge and a pair of (unlabeled) successor edges.  Merge
nodes are explicit, they have a pair of predecessor edges and a single

There is a distinguished (normal) entry node and a distinguished (special)
exit node with arbitrarily many predecessor edges and no successor edges.

The graph is intended to support graph-based analysis and transformation.
