f983244124 Remove unnecessary AST node for ++ and -- operations. 
Instead of adding an extra AST node we can just use an auxiliary
bailout id for named and keyed property count operations.

302037d44e Make object groups and implicit references a bit more lightweight. 
We can only call malloc/free once per group and we can avoid scanning
through a list of NULLs if we keep unprocessed groups in the beginning.

I also changed the internal representation of implicit references to
hold a handle to the parent (instead of a direct pointer). The
prologue callback must not trigger a GC, but it's better to be safe.

c9904976f9 Simplify isolates access during stack iteration (WAS: Move SafeStackFrameIterator::active_count_...) 
While trying to fix Mac and Windows versions for this change:
http://codereview.chromium.org/6771047/, I figured out, that we
already store an isolate in StackFrameIterator, so we can use it in
frame objects, instead of requiring it from caller.

I've changed iterators usage to the following scheme: whenever a
caller maintains an isolate pointer, it just passes it to stack
iterator, and no more worries about passing it to frame content
accessors.  If a caller uses current isolate, it can omit passing it
to iterator, in this case, an iterator will use the current isolate,
too.

There was a special case with LiveEdit, which creates
detached copies of frame objects.

ea8312ba33 Reapply: Never use classic code generator. 
Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.

This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

2531480d10 Re-establish mips basic infrastructure. 
This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.

All other mips arch files are replaced with stubbed-out versions that
will build.

Arch independent files are updated as needed to support building and
running mips.

The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

67f20c4d95 Set optimizable to false on code object if shared function info says so. 
Because we might throw away code when doing code flushing we need to
set the optimizable flag to false in CompileLaze if this has been set
on the shared function info. This is the only place where this can
happen, since we always exchange the code with the laze compile stub
when doing code flushing.

The comment in AbortAndDisable actually states that this is already
the case (and that comment should now be ok).

963a75cc09 Fast TLS support. 
This patch adds common infrastructure for fast TLS support and
implementation on win32. More implementations will be added soon.

Fast TLS is controlled by V8_FAST_TLS define which is enabled by
default in our gyp and scons builds. The scons build has
fasttls={on,off} option so that we can see the effects of slow TLS
when needed.

3925045f70 Don't rely on C++ object padding across platforms 
The use of sizeof on FrameDescription to get to the additional allocated memory for the frame content relies on the padding of the FrameDescription. On IA32 Linux the FrameDescription is not padded but on ARM Linux it is padded to become 8 byte aligned. With a snapshot generated with the ARM simulator on IA32 Linux that contains one or more of the deoptimization tables the deoptimization did not work as the access to the frame content was one off between the C++ code and the generated code.

cdf65ca087 Reimplement the padding of relocation information for lazy deoptimization on ia32. 
The previous implementation attempted to keep track of the needed
relocation size for deoptimization while generating the optimized
code. That was error prone. This patch moves the relocation resizing
to the deoptimizer as the last step of creating an optimized code
object.

The down side to this approach is that two relocation information byte
arrays are created for all optimized functions that do not have enough
relocation space for lazy deoptimization.

This change adds a new IR instruction for polymorphic loads. It performs
map compares and loads in one IR instruction instead of splitting each
load into a graph of map-compares and field loads.
 
The advantage is a smaller IR and less basic blocks, plus it allows to

a224db3a50 X64: Optimize access to external references. 
Access to an ExternalReference in non-serializable code will try to use
an offset relative to the root-array register.
Since the root-array is in the Heap object, and the Heap object is in
the Isolate object, there's a good chance that any external data field
is within a 32-bit offset of the root array register.
It falls back on the original behavior if the serializer is enabled,
if the root register isn't initialized or if the offset is not representable
as a 32-bit value.

avoid TLS access in connection with external references.

Make the isolate accessible via the assembler.

Only for ia32 at this point. If this looks OK to you I will port it.

8066271fd2 Optimize calls to object literal properties that are initialized with a function literal. 
This allows fast calls and inlining of functions like:

var o = {f: function() { return "foo"; }}
o.f();


Object literals that contain function literals are initially created a dictionary mode
object and only transformed to fast properties once all properties are computed and
added. This allows us to create constant function properties for functions declared
inside the object literal. Function literals inside object literals are marked for
pretenuring so that they work as contant function properties.

Object literals without functions should just function as before.

e820926108 Improve ARM-Simulator. 
This patch
- removes the unimplemented code crash when rendering invalid/unknown instructions and prints "unknown" instead.
- prints the beginning of the constant pool marker.
- adds "da" as a shortcut for "disasm".
- print hexadecimal representation of double and single registers. This makes it easier to debug move/conversion code that uses temporary int32 values in floating point registers.
- annotates the stack with short prints of the values (HeapObjects and smis),
- makes disasm take an address or a register as second argument without a third argument, which defaults to printing ten instructions.

c6e37c5dfb Make Script.prototype.nameOrSourceURL use indexOf search first before trying to match with a RegExp. 
This should use Boyer-Moore search with a long string, which is potentially
faster than RegExp search.
The target string is typically, but not guaranteed, at the end of the
source, so for long sources, there will be a lot of characters to skip.

4722f692e4 Make exception thrown via v8 public API propagate to v8::TryCatch as JS thrown exceptions do. 
Correctly process failures which can be returned by Object::GetProperty
when performing GetRealNamedProperty* queries.

Callback properties can produce exceptions so we need to wrap access to them
into exception checks.  However, despite of many other methods with exception
checks, property access doesn't mandatroy go via JavaScript and hence we
need to inject code to propagate exception to public API TryCatch handlers.

On ARM the break at break slots wrongly used the break at return stub which assumes an object opinter in r0. At break slots there are no objects live in registers so a GC while at a break on a break stub could cause a crash as r0 was wrongly pushed on a internal frame to be handled by GC.

fa9e57e326 Change __defineGetter__ and __defineSetter__ to respect non-configurable. 
This makes us compatible with firefox. Earlier on we were somehow
compatible with safari - which will allow defining a getter even when
an existing getter is present and non-configurable. We would, however,
in addition to overwriting the getter also change configurable to
true. The approach used by firefox seems much more sound, i.e., why
should it be possible to use __defineGetter__ or __defineSetter__ to
overwrite a non-configurable getter or setter respectively.

I will file a bug on the webkit bugtracker.

d57a8b0a07 X64: Change kSmiConstantRegister to r12. 
We never use the smi register in places where it matters that r12 as
a base register needs an extra SIB byte. Might as well free up the
unencumbered r15 register instead.

83616da7f5 Rebuild scope chain from serialized scope info before parsing lazily. 
We used to rebuild it in Scope::Analyze but this might lead to mismatch between scopes seen by parser during the first and the second parse of the function.

9cca7d2733 Combine typed and pixel arrays. 
Worth mentioning:
- Specialized versions of pixel array and store/loads inside the generic stubs have been removed, since to have parity for all external arrays, 8 different versions would have to be inlined/checked.
- There's a new constant in v8.h for external arrays with pixel array elements.
