a083601e73 Record allocation stack traces
This is initial implementation of allocation profiler.

Whenever new object allocation is reported to the HeapProfiler and allocation tracking is on we will capture current stack trace, add it to the collection of the allocation traces (a tree) and attribute the allocated size to the top JS function on the stack.

Format of serialized heap snapshot is extended to include information about recorded allocation stack traces.

This patch is r17301 plus a fix for the test crash in debug mode. The test crashed because we were traversing stack trace when just allocated object wasn't completely configured, in particular the map pointer was incorrect. Invalid Map pointer broke heap iteration required to find Code object for a given pc during stack traversal. The solution is to insert free space filler in the newly allocated block just before collecting stack trace.

f2122438e0 Removed long-running obselete test case.
The test was the 2nd longest-running test case in debug mode, and the
stuff it tests has already been moved long ago to some other place,
which is in turn heavily tested by far simpler and faster things
(%TruncateString etc.).

e25920da19 Make Array.prototype.pop throw if the last element is not configurable.
Popping an element from an array should call [[Delete]] internal method
and pass true as the second argument (ECMA-262/5.1/#sec-15.4.4.6).
When the last element can't be deleted, throw a Type Error.
Not throwing the error would result in endless loop in the following test.

TEST=var a=[];Object.defineProperty(a,0,{});while(a.length)a.pop();

By the way fix another bug, or else i can't post any issues.
"presubmit.py" throw a "missing a correct copyright header" on windows.
Both the slash and the backslash are valid path separator on windows.

bdeaf7514a Enable preaging of code objects when --optimize-for-size.
This change means that code which is never executed is garbage collected immediately, and code which is only executed once is collected more quickly (limiting heap growth), however, code which is re-executed is  reset to the young age, thus being kept around for the same number of GC generations as currently.

3769a2d24d TransitionAndStoreStub bailout needs to transition (and store).
Performance regression found in test regress-2185-2.js. The problem was
that the bailout method for TransitionAndStoreStub was not performing
the appropriate transition.

19d716989e Unify handling of position info in AST, part 1
* AstNode now has a position info.
* Removed various ad-hoc position infos from subclasses (most of which had it).
* Position is always set with the constructor, instead of later.
* Take care to use kNoPosition in the right spots, to not crash the debugger.

Still to do:

* Eliminate Conditional::then/else_position and WhileStatement::condition_position.
* Make CaseClause a proper AstNode and eliminate its custom position.
* If possible, eliminate all uses of kNoPosition.

ECMA262 5.1th, v8::Function::Call and Object::CallAsFunction should take
v8::Value as a receiver instead of v8::Object.

53194b44ba Allocation site tests aren't compatible with GcStress mode.
They make assumptions about elementskind of arrays based on allocation site
feedback. This feedback is highly dependent on mementos, unrooted objects
placed behind arrays in the heap meant to live until the next scavenge.

GcStress does many more gcs than normal, and wrecks havoc with this kind
of test.

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.

2fdadd7794 Drop OS::IsOutsideAllocatedSpace() and move the tracking to the MemoryAllocator.
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.
