Correct handling of adding a string and a smal integer
...
The fast case of looking up the string convertion of the smi did not handle the case where left/reghe operands could be in eax/edx instead of edx/eax which is the default.
Also got rid of creating an internal frame for calling string and instead patched the argument on the stack and performed a tail call.

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.

code but never used. Remove this pass and the data structures it
builds.
The representation of variable usage for Variables has been changed
from a struct containing a (weighted) count of reads and writes to a
simple flag. VariableProxies are always used, as before. The unused
"object uses" is removed.

Initial implementation of an edge-labeled instruction flow graph.
...
The flow graph is built by walking the AST. Edges are labeled with
instructions (AST nodes). Normal nodes have a single predecessor edge and a
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
(unlabeled) successor edge.
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.
