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.

Since the per-context random number generator is now

call into the C function (which means we don't need
to MarkAsCall anymore).

Improve code generation for the HRandom instruction.
...
Since the per-context random number generator is now
properly seeded upon context creation, we do not need
to check for lazy-initialization anymore, and so we
can implement the HRandom instruction w/o having to
call into the C function (which means we don't need
to MarkAsCall anymore).

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.

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).

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.

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

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.

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.

InstallOptimizedCode aquires ownership on the compilation info and deletes
it on return, tearing down the attached zone. The OptimizingCompiler
object is a zone object allocated in just that zone, so it also gets
deleted. Effectively, InstallOptimizedCode cleans up when it's done, so
the OptimizingCompiler object it receives is invalidated afterwards.
