c203f05474 Delivery logic for Object.observe
This CL has two parts: the first is the logic itself, whereby each observer callback is assigned
a "priority" number the first time it's passed as an observer to Object.observe(), and that
priority is used to determine the order of delivery.

The second part invokes the above logic as part of the API, when the JS stack winds down to
zero.

Added several tests via the API, as the delivery logic isn't testable from a JS test
(it runs after such a test would exit).

63f033576c Fix performance regressions due to lazy initialization.
This CL:
- Adds a new trait parameter to LazyInstance to let it initialize the instance
  without paying the cost of atomic operations (which are expensive on Mac).
  This only works for users who don't care about thread-safety and this is now
the default initialization trait used by LazyInstance in v8.

- Reverts the changes that were made in r11010 in isolate.{cc,h}. That lets
  Isolate's accessors be as cheap as they were before (but adds one static initializer).

- Adds OS::PostSetup() used to initialize the math functions which depend on CPU features.
That lets the math functions get rid of CallOnce().

a3eccef3fa Valgrind cleanliness, part 1: Delete current isolate on exit.
Currently we leak 140kB from 80 allocation sites when we evaluate a simple
"print(1+2)" in d8 and exit. This might not be a real problem in Chrome because
most of the time the whole process containing v8 vanishes, but it can hide real
leaks in a sea of false positives. Therefore, this CL and a few subsequent ones
clean this up a bit.

This simple CL alone fixes 45 leaks, leaving only 35 with a net loss of 2192
bytes (on ia32).

1f7d42efc9 Landing for pliard@chromium.org: Remove static initializers in v8.
This change includes two CLs by pliard@chromium.org:

1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):

Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances are never deleted).

This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/



2.  http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.

With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This static initializer populates a structure used by x86 atomic operations. It seems that we can hardly remove it. If possible, it will be removed in a next CL. 

This CL also modifies the presubmit script to check the number of static initializers.

bdf6895bb3 Encapsulate element handling into a class keyed on ElementsKind
Advantage is that it's much easier to add new element types (like FAST_SMI_ELEMENTS), and that handling logic for each element kind is (more) consolidated.

Currently, only GetElementsWithReceiver uses the new encapsulation, but the goal is to move much more element functionality into the class incrementally.

ea8312ba33 Reapply: Never use classic code generator.
Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.

This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

48066af7e0 Landing for Justing Schuh.
Split out the random number state between JavaScript and private API

I've added v8::RandomPrivate() for internaly used random numbers, and pass the state in as a parameter to a random_base function.

I still need to implement strong seeding. I already know how and will be landing that in another patch.

BUG=http://code.google.com/p/v8/issues/detail?id=936
TEST=None.

9640b6d9ab Allow forcing the use of a simulator from the build script
independently of the host architecture.

Fix build issue for the mips simulator.  The mips simulator does not
currently work, but at least this change does not make it worse.
