4dca23f825 Added a Isolate* parameter to Serializer::enabled().
This parameter will soon be used when a few pseudo-classes like
Serializer are turned into real classes. The current CL is already big
enough, untying our Gordian knot called "startup" will continue...

cd5ea74700 Replace 'operator*' with explicit 'get' method on SmartPointer
Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.

Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.

Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.

b320dfcf58 Reland^2 "Add Chromium-style TimeDelta, Time and TimeTicks classes, and a new ElapsedTimer class."
These classes are meant to replace OS::Ticks() and OS::TimeCurrentMillis(),
which are broken in several ways. The ElapsedTimer class implements a
stopwatch using TimeTicks::HighResNow() for high resolution, monotonic
timing.

Also fix the CpuProfile::GetStartTime() and CpuProfile::GetEndTime()
methods to actually return the time relative to the unix epoch as stated
in the documentation (previously that was relative to some arbitrary
point in time, i.e. boot time).

The previous Windows issues have been resolved, and we now use GetTickCount64()
on Windows Vista and later, falling back to timeGetTime() with rollover
protection for earlier Windows versions.

102c5170c2 Fix bug introduced by r13960.
Allocator does not backtrack thus during allocation we must not create an unhandled live
range which starts before the start of the current live range.

If such range is added to the list of unhandled it might see an inconsistent state of active/inactive live-ranges as they are retired to handled as soon as start of the current live range is larger than their end.

Add assertion to catch this kind of bugs early.

c1ee1b457f Break Crankshaft into phases.
Crankshaft now runs by calling CreateGraph on the HGraphBuilder, then
calling Optimize and Codegen on the HGraph.

6125718f37 Remove TLS access for current Zone.
By passing around a Zone object explicitly we no longer need to do a
TLS access at the sites that allocate memory from the current Zone.

f46906d7a8 Reduce size of LIR instruction by one word and remove dead code.
Until now we always recorded two deoptimization environments for instructions
that are marked as calls. We actually don't need two for all LIR
instructions except one (LInstanceOfKnownGlobal) where there is a lazy
deoptimization point in deferred code.

This change remove on of them and uses one virtual function instead
to make LInstanceOfKnownGlobal work as before.

Additionally, this change removes an unused predicate save_doubles_ from LIR
instructions and removes some helper functions that are used only in one place.

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.

a8980079a0 Add flag --trace-phase to selectively produce IR trace output.
By default --trace-hydrogen only generates the final IR (before
code generation). The other phases can be printed by specifying
them by their first letter. Currently H=HIR, L=LIR or Z=final IR (default)
are recognized.
