98db16d94f Progress towards making Zones independent of Isolates and Threads. 
This CL changes some parts of the code to explicitly pass around a
Zone.  Not passing in a zone is okay too (in fact most of v8 still
doesn't), but that may incur a TLS lookup.

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().

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.

90c9f1b989 Suspend runtime profiler as soon as we exit JS. 
Lots of web pages have really frequently firing timers that keep the
profiler thread spinning if we require a period of JS inactivity
before suspending the profiler. While it's possible to throttle it by
increasing the sleep delay and adjusting the duration of the required
inactive period, it seemed much simpler to just stop it immediately on
exiting JS.

Stopping the profiler this way effectively turned off two optimization
heuristics: 1) eager optimization (it's reset on waking up the
profiler and now the profiler wakes up much more frequently) and 2)
optimization throttling based on JS to non-JS state ratio (the ratio
is now 100%). I removed these two heuristics and found no performance
regressions so far.

508b22c436 "Deiceolate" Thread classes. 
Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.

This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.

As a side effect, we have also fixed the DebuggerAgent test.

Thanks to Vitaly for help in fixing isolates handling!
