b66afe30fe Add a basic gn file for V8
Currently, the gn support is incomplete and only works from within a
chromium checkout.

See https://code.google.com/p/chromium/wiki/gn for details

We move the BUILD.gn file to v8 nevertheless to make renaming files
easier, as the chromium CQ already now checks the gn build.

785bdf7c1e Don't add code dependencies eagerly for HCheckMaps.
Instead of adding code dependencies on stable during
graph creation, we now add them during code generation
for those HCheckMaps that survived dead code elimination.

7c1036d424 Various cleanups in check elimination.
- Move IsMapAccess() to HObjectAccess.
- Collect the actual objects instead of HStoreNamedFields in
  effects, and also consider HTransitionElementsKind.
- Fix ownership of HCheckMaps::maps() and HLoadNamedField::maps().
- Avoid heavy copying of the same map sets all the time during
  check elimination, and do something useful with the memory
  instead by slightly bumping the maximum number of tracked
  objects.
- Slightly optimize UniqueSet::Contains().

b41af2c63f Version 3.26.30 (based on bleeding_edge revision r21129)
Introduce a microtask suppression scope and move microtask methods to isolate (Chromium issue 369503).

Re-enable Object.observe and add enforcement for security invariants.

Move cache line size calculation directly into CPU::FlushICache (Chromium issue 359977).

Generation of our home-grown memmove doesn't depend on serializer state anymore (Chromium issue 359977).

Fix |RunMicrotasks()| leaking reference to the last context being run on.

Object.defineProperty shouldn't be a hint that we're constructing a dictionary (Chromium issue 362870).

Performance and stability improvements on all platforms.

5ea893074c Fix ObjectNotifierPerformChange leak after r21126
Due to overlapping names of natives and runtime functions, the wrong
context was used for Notifier.prototype.performChange. The leak test
has been augmented to properly cover the leaky case, and the test
now passes.

Also tightened up type checks in runtime.cc and removed Object.observe
functions from knownIssues in fuzz-natives-part2.js.

1b270ef5ea Re-enable Object.observe and add enforcement for security invariants.
This patch reverts r21062 which disabled Object.observe and the relevant tests.

It also adds enforcement for the following three invariants:

1) No observer may receive a change record describing changes to an object which is in different security origin (context have differing security tokens)

2) No observer may receive a change record whose context's security token is different from that of the object described by the change.

3) Object.getNotifier will return null if the caller and the provided object are in differing security origins

Further, it ensures that the global object can never be observed nor a notifier retrieved for it.

Tests are included.

461bb09b4a Move cache line size calculation directly into CPU::FlushICache.
This disentagles the initialization/dependency mess quite a bit and
makes things vastly simpler. If the 'mrs' on every flush is too
expensive (which it is hopefully not), the cache line sizes will have
to be instance variables of the CPU class and FlushICache will have to
be a member function. This would involve some more or less tricky
refactorings, which we shouldn't do until we are *really* forced to
do.

5170a008d3 Generation of our home-grown memmove doesn't depend on serializer state anymore.
The serializer state has to be per-Isolate, but at the point where we
generate our memmoves we don't really have an Isolate. Furthermore,
there was no fundamental reason why we shouldn't use our home-grown
memmove during mksnapshot time.

Perhaps we can totally remove our own memmove nowadays, but this would
be a separate CL.

50d8259fea Fix crash in debug builds introduced with r21110.
Basically we should not check for map deprecation during
code selection, because that may run on the concurrent
compiler thread. So the fix is to move this logic to the
code generation phase instead, which is always run on the
main thread.

570fd74fc0 Fix |RunMicrotasks()| leaking reference to the last context being run on.
RunMicrotasks() executes pending tasks and swaps the old array with a new array. However, the new array contains the reference to the current context as its creation context. This prevents the context from gc-ed until RunMicrotasks() is executed in the different context.
