ARM: Makefile/gyp update allowing better control of ARM specific options.

This patch defines new makefile command line paramaters to better control the
ARM specific options. The new paramters are
* armfpu      = vfp, vfpv3-d16, vfpv3, neon.
* armfloatabi = softfp, hard
* armneon     = on
* armthumb    = on, off
* armtest     = on
One existing paratemer has been modified:
* armv7       = true, false
A number of parameters have been deprecated (but are still working):
* hardfp      = on, off
* vfp2        = off
* vfp3        = off

the armtest paratmer when set to "on" will lock the options used during compile
time at runtime. This allows for example to easily test the ARMv6 build on an
ARMv7 platform without having to worry about features detected at runtime. When
not specified the compiler default will be used meaning it is not necessary
anymore to specify hardfp=on when natively building on an hardfp platform.

The shell help now prints the target options and features detected.

pthreads seem to be fully supported on Linux and Android which allows to remove many #ifdefs.

Also OS::Sleep(interval_) is used to pause sampling thread on all platforms. It makes no sense to send signal once 900mks to compensate 100mks delay on signal delivery as the signals would be delivered once 900mks.

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.

Move *BSD and Solaris Sampler implementation into sampler.cc

This is a first step to having profiler sampler implementation in one file with platform capabilities guarded with #ifdef. Otherwise we have very similar implementations scattered over platform-*.cc files which makes it hard to see differences and make changes.

The next steps will be to merge win32, Mac OS X and Cygwin implementations into sampler.cc They suspend profiled thread instead of sending a signal but apart from that the logic is pretty much the same. Then I'm going to move sampler-related code from log.* into sampler.*

presubmit.py tried to execute cpplint.py directly, but in Windows it's the shell that connects that to the python binary so the execution (subprocess.Popen) needs to be told how to find python. An alternative would be to call subprocess.Popen with shell=True but this is less dangerous.

Intel VTune integration for V8/d8

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.

Remove code that analyzes tos values from tickprocessor

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.

Fix detection of indexed properties in Object.defineProperty()

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.

MIPS: Accurate function prototypes for native calls from ARM simulator.

Port r14230 (76c22097)

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.
