Expose debug context into the native code. This change is doing several things:
...
1) Exposes Local<Context> v8::Debug::GetDebugContext().
Rationale: We can already get debugger context instance using various workarounds,
so exposing it explicitly in the API only makes things more clear.
2) Removes debugger.HasJavaScriptFrames() requirement for entering debugger context.
Rationale: Sometimes we'd like to call into debugger from the external native code.
3) Makes Debugger v8::Debug::Call execute on debugger context's global object.
Rationale: This is somewhat arguable, but temporary measure. We've agreed that we
should introduce a DebugAPI object that would expose necessary API in the debug-delay.
The problem is that it would take some time to define this API and it is not really
convenient to do that on the v8 land given the difference in v8 / host lifecycle.
The plan is to compose this API as a Debug.* wrapper outside v8 by means of exposing
debugger context's global object here, and once API settles down, upstream it to v8 and
start making Debug::Calls on this new DebugAPI object instead.

Fix pop push optimization to work with partial snapshots (correct
...
registration of external references in Proxy objects).
I moved the declaration of the two functions to stub-cache.h
because with all the types they use it's hard to declare them
anywhere else. But the actual definition is still in runtime.cc
near to the place where they are used.

Inline floating point compare
...
Inline floating point compare instead of calling the stub when the following conditions are met:
* Code is in a loop
* Compare is not a for loop condition
* Compare is not an equal comparison
This inlined code handles heap number to heap number and heap number to smi compare. It can also handle smi to smi compare, but whenever there is a chance of comparing two smis the smi compare is inlined before the inlined floating point compare. Support for non SSE2 hardware is included.
A new set of variants of the compare stub without the floating point comparison code is called if the inline comapre fails due to the operands not beeing heap numbers or smis.
The virtual frame has been extended with a branch taking two live results to be carried through to the destination. This makes this change much simpler as the inlined code have two live results in registers and a number of bailouts.
CompareStub::GetName needs to be updated as well. I will do that as a separate change.
Also inlined equality check if both operands can't be NaN. This can only provide positive equals if it is the same object.

String search performance improvements:
...
* Using memchr for first/only char lookup is faster than hand-coded
loop. It processes one machine word per iteration so it helps even
more on x64.
* Tweaked badness computation in simple search. We pay only for the
first char memchr scans, not for all of them.

Add a predicate IsPrimitive to AST Expression nodes.
...
IsPrimitive reflects that an expression's value is known statically to
be one of the ECMA-262-3 JS types other than Object (e.g., Undefined,
Null, Boolean, String, or Number).
The type conversions ToPrimitive, ToNumber, ToInteger, ToInt32,
ToUInt32, ToUint16, ToString, or ToObject cannot invoke user code for
primitive input values. ToObject throws a TypeError if its input is
Undefined or Null.

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

Also: two small changes to flow graph printing. Children of branch

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.

Refactor the code cache to handle large number of properties on the global object (take 2).
...
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.
The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.
This is a remake of r3952 (http://codereview.chromium.org/652119 ) which have the additional ability to look for the index of code stubs for access to the global object.

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.

Added zone-inl.h to jsregexp.h since it relies on calling new ZoneList which again relies on calling the static new method on Zone (defined in zone-inl.h but declared in zone.h).

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.

Remove unneeded variable usage analysis.
...
A variable usage analysis pass was run on toplevel and lazily-compiled
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.
