In this patch, we added the JIT code event handler for Vtune. Most of the code is in the
folder src/third_party/vtune. Two APIs are added in include/v8.h to get the requirement info
from V8.

We add the v8_enable_vtunejit parameter for GYP to enable these Vtune code compilation.
vTune::InitilizeVtuneForV8() is invoked in the embedder of V8 to make sure it's invokded if
vtune support is enabled.

Assuming that the value on top of stack is return address for a frameless invocation is error-prone. Corresponding logic was removed from profile-generator.cc in r14205 (see https://code.google.com/p/v8/source/diff?spec=svn14205&r=14205&format=side&path=/branches/bleeding_edge/src/profile-generator.cc) and now it is time to remove it from the tick processor.

Since the tos is not used anymore by profiler it is also removed from TickSample.

This is just shuffling some code around to make comparing the platform files easier.

Made cygwin/nullos support a bit more complete on the way.

This adds support to the stack guard to trigger a full deoptimization of
all optimized code when the GC kicks into high promotion mode. Global
pretenuring decisions in optimized code can then be based on the high
promotion mode.

When defining an indexed property on an Array object, the object's
length property should (perhaps) be updated.  This was done for any
property for which

  ToUInt32(name) == ToNumber(name)

was true, meaning any property name that, when converted to a number,
was an integer in the range [0, 2^32).  The detection should be more
strict; an indexed property is one for which

  ToString(ToUInt32(name)) == name

is true only.

Original commit message:
Native method invocation from the arm/simulator-arm.cc previously made
non-portable assumptions about calling conventions. This was okay for 32-bit
stack-based machines, where by-value structs are automatically materialized
on the stack, and where both int and double parameters could be passed on the
stack. However they are not okay for x86-64, which has an elaborate scheme
for passing parameters in registers.

This CL replaces the previous non-portable code paths with portable code,
using call-sites that accurately match the prototype of the callee.

This makes the logic in the Hydrogen->Lithium translation much clearer, avoids a
hand-written dispatch and even opened up opportunities for simpler register
constraints for some operations/platforms.

Doing the same for the Hydrogen level might be done in a follow-up CL.
