9f5edd1bb2 Make v8 compile on VS2013. 
VS2013 contains a number of improvements, most notably the addition of all C99 math functions.

I'm a little bit concerned about the change I had to make in cpu-profiler.cc, but I spent quite a bit of time looking at it and was unable to figure out any rational explanation for the warning.  It's possible it's spurious.  Since it seems like a useful warning in general though, I chose not to disable globally at the gyp level.

I do think someone with expertise here should probably try to determine if this is a legitimate warning.

2abe14b8f6 HeapProfiler: replace pointer based matching algorithm with string matching algorithm for strings_ member. 
pros: decreased snapshot size.
cons: increased serialization time.

I've tested the implementation on gmail 90mb heap.
I saw no speed degradation on the serialization step.
The snapshot size lost ~3% of its size. 100Mb -> 97Mb.

0e8e003077 Implement in-place rehashing of HashTable. 
The algorithm puts elements into correct positions in  multiple iterations.
On the first iteration it tries to put elements at entries specified by
their first hash probe. On the second iteration -- by the second
hash probe, and so on. Overall it does O(k*n) memory accesses, where
k is the maximum number of probes required for an element and n is the
capacity of the hash table. The expectation is that k will be small.

ebd4b61f38 Add access check for observed objects 
This change is mostly straightforward: for 'normal' sorts of change records,
simply don't deliver a changeRecord to a given observer callback if an access
the callback's Context is not allowed to "GET" or "HAS" changeRecord.name on
changeRecord.object, or if ACCESS_KEYS is disallowed.

For 'splice' records, the question of whether to hand it to an observer is trickier, since
there are multiple properties involved, and multiple types of possible information leakage.
Given that access-checked objects are very rare (only two in Blink, Window and Location),
and that they are not normally used as Arrays, it seems better to simply not emit any splice
records for such objects rather than spending lots of logic to attempt to avoid information
leakage for something that may never happen.

Original descriptions were:
- "Refactor and cleanup VirtualMemory."
- "Fix typo."
- "Deuglify V8_INLINE and V8_NOINLINE."
- "Don't align size on allocation granularity for unaligned ReserveRegion calls."

Reasons for the revert are:
- Our mjsunit test suite slower by a factor of 5(!) in release mode.
- Flaky cctest/test-alloc/CodeRange on all architectures and platforms.
- Tankage of Sunspider by about 6% overall (unverified).

a797a35975 Refactor and cleanup VirtualMemory. 
Remove a lot of platform duplication, and simplify the virtual
memory implementation. Also improve readability by avoiding bool
parameters for executability (use a dedicated Executability type
instead).

Get rid of the Isolate::UncheckedCurrent() call in the platform
code, as part of the Isolate TLS cleanup.

Use a dedicated random number generator for the address
randomization, instead of messing with the per-isolate random
number generators.

9139e1a864 This patch implements optimized objectInfo structure which manages the set of observers associated with an object and the changeRecord types which they accept. 
Observation in the normal case (Object.observe, default accept types, one observer) now allocates fewer objects and unobservation no longer needs to scan and splice an InternalArray -- making the combined speed of observe/unobserve about 200% faster.

This patch implements the following optimizations:

-objectInfo is initially created without any connected objects or arrays. The first observer is referenced directly by objectInfo, and when a second observer is added, changeObservers converts to a mapping of callbackPriority->observer, which allows for constant time registration/de-registration.

-observer.accept and objectInfo.performing are conceptually the same data-structure. This is now directly represented as an abstract "TypeMap" which can later be optimized to be a smi in common cases, (e.g:   https://codereview.chromium.org/19269007/).

-objectInfo observers are only represented by an object with an accept typeMap if the set of accept types is non-default

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.

f6b7ec4da0 HeapProfiler: very slow ~4min "take snapshot time" for 80MB gmail heap. 
The reason of that is a number of cons strings in the app.
The app constructs a json string and as a result v8 heap has
a very long chain of cons strings.

Profiler counts all these strings as plain String objects and
assign the content of the strings as node names.

It required O(n^2) time and O(n^2) memory.

Solution: I introduced two new types, kConsString and kSliced string.
They do not use the content of the string for names. So the problem disappeared.

The heap profiler usability problem will be solved on Blink side.

24a0cabddc Use PAGE_NOACCESS for guard pages in Windows. 
Up until now we used PAGE_GUARD for guard pages in Windows, which
will raise a STATUS_GUARD_PAGE_VIOLATION exception on first access
and grant regular access afterwards. This behavior is required to
implement automatic stack checking, or more generally to implement
applications that monitor the growth of large dynamic data structures.

However, this is not what we want for our guard pages, which are
used as a security mechanism. What we really want is PAGE_NOACCESS
here, which is the Windows-equivalent of PROT_NONE that we use on
all other platforms.

43780dbdc9 Check if timeout has expired after processing each sample 
To avoid long intervals between taking samples due to processing all accumulated samples at once, the samples are processed one by one and we check if the sampling interval has elapsed after each step rather than after processing all the samples in the queue.

This is a modified version of r16549 whith a fix for test flakiness. The test flakiness introduced by the previous version of this changed was fixed by changing return type of ProfilerEventsProcessor::ProcessOneSample from bool to enum with 3 options. In the main profiling loop we decide that the next code event should be processed when sample with a greater ordinal number is encountered. When processing remaining samples we shouldn't wait for more samples and if the samples queue is empty we just process next code event.

bbd26abedb Functions may not be optimized and we would like to know in cpu profiler what was the reason. 
Current v8 implementation may disable optimization for a particular function or block it with help of dont_optimize flag.
The patch propagates the reason of that to the SharedFunctionInfo where cpu profiler can get it.

SharedFunctionInfo is a heap object so I extracted 8 bits from OptsCount for handling bailout reason code.

Instead of globally tracking allocated space limits, which was
not implemented properly anyway (i.e. lack of synchronization
on the reading side), track it per MemoryAllocator (that is
per heap/isolate).

In particular, avoid to call IsBadWritePtr() on Windows, it is
obsolete and Microsoft strongly discourages its usage.

b26d28d964 This patch implements optimized objectInfo structure which manages the set of observers associated with an object and the changeRecord types which they accept. 
Observation in the normal case (Object.observe, default accept types, one observer) now allocates fewer objects and unobservation no longer needs to scan and splice an InternalArray -- making the combined speed of observe/unobserve about 200% faster.

This patch implements the following optimizations:

-objectInfo is initially created without any connected objects or arrays. The first observer is referenced directly by objectInfo, and when a second observer is added, changeObservers converts to a mapping of callbackPriority->observer, which allows for constant time registration/de-registration.

-observer.accept and objectInfo.performing are conceptually the same data-structure. This is now directly represented as an abstract "TypeMap" which can later be optimized to be a smi in common cases, (e.g:   https://codereview.chromium.org/19269007/).

-objectInfo observers are only represented by an object with an accept typeMap if the set of accept types is non-default

281de965a4 Import ConditionVariable class. 
Condition variables are synchronization primitives that can be used
to block one or more threads while waiting for condition to become
true.

Right now we have only semaphores, mutexes and atomic operations for
synchronization, which results in quite complex solutions where an
implementation using condition variables and mutexes would be straight
forward.

There's also a performance benefit to condition variables and mutexes
vs semaphores, especially on Windows, where semaphores are kernel
objects, while mutexes are implemented as fast critical sections,
it CAN be beneficial performance-wise to use condition variables
instead of semaphores.
