4dca23f825 Added a Isolate* parameter to Serializer::enabled(). 
This parameter will soon be used when a few pseudo-classes like
Serializer are turned into real classes. The current CL is already big
enough, untying our Gordian knot called "startup" will continue...

2fe0f48d39 Simplified CPU/CpuFeatures a bit. 
This is a necessary intermediate step to disentangle the startup.

In the long run CPU and CpuFeatures should probably be merged,
and Serializer::enabled usage should be radically reduced, but
we're not there yet.

8f170a66e7 Improve positions tracking inside the HGraphBuilder. 
Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).

This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.

Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.

Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.

Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.

In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.

99ce5a2484 The current 
version is passing all the existing test + a bunch of new tests
(packaged in the change list, too).

The patch extends the SlotRef object to describe captured and duplicated
objects. Since the SlotRefs are not independent of each other anymore,
there is a new SlotRefValueBuilder class that stores the SlotRefs and
later materializes the objects from the SlotRefs.

Note that unlike the previous implementation of SlotRefs, we now build
the SlotRef entries for the entire frame, not just the particular
function.  This is because duplicate objects might refer to previous
captured objects (that might live inside other inlined function's part
of the frame).

We also need to store the materialized objects between other potential
invocations of the same arguments object so that we materialize each
captured object at most once.  The materialized objects of frames live
in the new MaterielizedObjectStore object (contained in Isolate),
indexed by the frame's FP address.  Each argument materialization (and
deoptimization) tries to lookup its captured objects in the store before
building new ones.  Deoptimization also removes the materialized objects
from the store. We also schedule a lazy deopt to be sure that we always
get rid of the materialized objects and that the optmized function
adopts the materialized objects (instead of happily computing with its
captured representations).

Concerns:

- Is the FP address the right key for a frame? (Note that deoptimizer's
representation of frame is different from the argument object
materializer's one - it is not easy to find common ground.)

- Performance is suboptimal in several places, but a quick local run of
benchmarks does not seem to show a perf hit. Examples of possible
improvements: smarter generation of SlotRefs (build other functions'
SlotRefs only for captured objects and only if necessary), smarter
lookup of stored materialized objects.

- Ideally, we would like to share the code for argument materialization
with deoptimizer's materializer.  However, the supporting data structures
(mainly the frame descriptor) are quite different in each case, so it
looks more like a separate project.

Thanks for any feedback.

868ad01ecb This is a preview of the captured arguments object materialization,

containing frames' FixedArrays with their captured objects.)

19d832719e This is a preview of a first step towards unification of the hydrogen 
call machinery.  The change replaces CallNamed, CallKeyed,
CallConstantFunction and CallKnownGlobal hydrogen instructions with two
new instructions with a more lower level semantics:

1. CallJSFunction for direct calls of JSFunction objects (no
   argument adaptation)

2. CallWithDescriptor for calls of a given Code object according to
   the supplied calling convention.

Details:

CallJSFunction should be straightforward, the main difference from the
existing InvokeFunction instruction is the absence of argument adaptor
handling. (As a next step, we will replace InvokeFunction with an
equivalent hydrogen code.)

For CallWithDescriptor, the calling conventions are represented by a
tweaked version of CallStubInterfaceDescriptor. In addition to the
parameter-register mapping, we also define parameter-representation
mapping there. The CallWithDescriptor instruction has variable number of
parameters now - this required some simple tweaks in Lithium, which
assumed fixed number of arguments in some places.

The calling conventions used in the calls are initialized in the
CallDescriptors class (code-stubs.h, <arch>/code-stubs-<arch>.cc), and
they live in a new table in the Isolate class. I should say I am not
quite sure about Representation::Integer32() representation for some of
the params of ArgumentAdaptorCall - it is not clear to me wether the
params could not end up on the stack and thus confuse the GC.

The change also includes an earlier small change to argument adaptor
(https://codereview.chromium.org/98463007) that avoids passing a naked
pointer to the code entry as a parameter. I am sorry for packaging that
with an already biggish change.

Performance implications:

Locally, I see a small regression (.2% or so). It is hard to say where
exactly it comes from, but I do see inefficient call sequences to the
adaptor trampoline. For example:

;;; <@78,#24> constant-t
bf85aa515a     mov edi,0x5a51aa85          ;; debug: position 29
;;; <@72,#53> load-named-field
8b7717         mov esi,[edi+0x17]          ;; debug: position 195
;;; <@80,#51> constant-s
b902000000     mov ecx,0x2                 ;; debug: position 195
;;; <@81,#51> gap
894df0         mov [ebp+0xf0],ecx
;;; <@82,#103> constant-i
bb01000000     mov ebx,0x1
;;; <@84,#102> constant-i
b902000000     mov ecx,0x2
;;; <@85,#102> gap
89d8           mov eax,ebx
89cb           mov ebx,ecx
8b4df0         mov ecx,[ebp+0xf0]
;;; <@86,#58> call-with-descriptor
e8ef57fcff     call ArgumentsAdaptorTrampoline  (0x2d80e6e0)    ;; code: BUILTIN

Note the silly handling of ecx; the hydrogen for this code is:

84aa5263f3 Remove the last remnants of the TranscendentalCache. 
It was only used for Math.log, and even then only in full code and in %_MathLog. For crankshafted code, Intel already used the FP operations directly, while the ARM/MIPS ports were a bit lazy and simply called the stub. The latter directly call the C library now without any cache. It would be possible to directly generate machine code if somebody has the time, from what I've seen out in the wild it should be only about a dozen instructions.

4e439deb0b Support for the Linux 'perf report' and 'perf annotate' tools. 
In this change, the support comes in two flavours:

--perf_jit_prof - outputs the files in a new perf format that only works with a
patched perf tool (patch obtained from Stephane Eranian). Both 'perf report' and
'perf annotate' are supported (the file format also contains the machine code).

--perf_basic_prof - outputs the files in a format that the existing perf tool
can consume. Only 'perf report' is supported.

In both cases, we have to disable code compaction because the perf tool does not
understand code relocation. (We are told that code relocation should be
supported soon.)

Usage:

perf record -g d8 --perf_jit_prof --no_compact_code_space my.js
perf report

The change itself is straightforward - we simply listen to code events and
write an entry to a log file for every new piece of code.

I am not yet sure whether we should keep both versions or just one (and which
one). My hope is the reviewers can help here.

adae3f77ec Allow redirecting disassembly and deoptimization traces into a file. 
This is controlled by two flags:

--redirect_code_traces
--redirect_code_traces_to=<filename>

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

eb381b9444 Introduce a RandonNumberGenerator class. Refactor the random/private_random uses in Isolate/Context. 
The RandomNumberGenerator is a pseudorandom number generator
with 48-bit state. It is properly seeded using either

(1) the --random-seed if specified, or
(2) the entropy_source function if configured, or
(3) /dev/urandom if available, or
(4) falls back to Time and TimeTicks based seeding.

Each Isolate now contains a RandomNumberGenerator, which replaces
the previous private_random_seed.

Every native context still has its own random_seed. But this random
seed is now properly initialized during bootstrapping,
instead of on-demand initialization. This will allow us to cleanup
and speedup the HRandom implementation quite a lot (this is delayed
for a followup CL)!

Also stop messing with the system rand()/random(), which should
not be done from a library anyway! We probably re-seeded the
libc rand()/random() after the application (i.e. Chrome) already
seeded it (with better entropy than what we used).

Another followup CL will replace the use of the per-isolate
random number generator for the address randomization and
thereby get rid of the Isolate::UncheckedCurrent() usage in
the platform code.

97f8f91bb5 Fix call stack sampling for the case when native callback invokes JS function 
The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame.

Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.

00ed79fb8b Move FindCodeObject from Heap to Isolate. 
This removes the isolate=>heap=>isolate nonsense and has the additional bonus
that it re-enables printing of code objects in GDB. NOT: To make the latter
work, one has to adapt GDB any macros using FindCodeObject! Keeping things as it
is and outlining Isolate::heap() was not really an option...

Side note: Currently we are lucky that we still have Isolate::Current()
available in GDB, although it is marked as INLINE. :-}

53adf3b19c Add methods to allow resuming execution after calling TerminateExecution(). 
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::CancelTerminateExecution() -- When execution is terminated via a call
  to V8::TerminateExecution(), this method can be called to clear the
  termination exception so that the engine can continue to be used.

* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
  exception, HasTerminated() will return true to indicate it is valid to
  call V8::ResumeExecution() if desired.

A test case is added to cctest/test-thread-termination.cc.

9be937e6ed MIPS: fix NaN handling of Isolate::StackOverflow() 
The mjsunit/stack-traces-overflow.js test fails on MIPS target as Error.stackTraceLimit = NaN; should disable stack trace messages and Isolate::StackOverflow() assumes static_cast<int>(double NaN) < 0.

MIPS has a different NaN representation than other architectures so the NaN value casted to int is positive. This patch adds an isnan() check to make the handling of NaN uniform on all architectures.

55f93b5532 Renamed "symbols" to "internalized strings" throughout the code base, 
in preparation of the introduction of ES6 'symbols' (aka private/unique names).

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.

The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).
