Now that CpuProfiler sends does sampling on the profile event processing thread there is no need to launch sampler thread. The latter is used only for --prof profiler.

75e5a5a1a6 Support higher CPU profiler sampling rate on Windows 
This change moves sampling from SamplerThread to the profiler events processing thread and allows to configure sampling interval on Windows.

Custom tick counter is used instead of OS::Ticks as the latter has maximum presicion of 1ms while we need 100us. QueryPerformanceCounter is used to retrieve high-precision time as described in http://msdn.microsoft.com/en-us/library/ee417693(VS.85).aspx

1083d1f817 Remove deprecated profiler API 
This change removes --prof-lazy command line flag that was introduced for the old CPU profiler implementation in Chrome DevTools. DevTools now use profiler API defined in v8-profiler.h

This change also removes methods for pausing resuming --prof profiler. These methods were deprecated in v.3.20 (https://code.google.com/p/v8/source/browse/branches/3.20/include/v8.h#4629)

After this change the profiler will always start if --prof option is passed and can be stopped either in the tests or if write to log file fails.

e76482f2da Cleanup Mutex and related classes. 
Drop the previous Mutex and ScopedLock classes from platform files.

Add new Mutex, RecursiveMutex and LockGuard classes, which are
designed after their C++11 counterparts, so that at some point
we can simply drop our custom code and switch to the C++11
classes. We distinguish regular and recursive mutexes, as the
latter don't work well with condition variables, which will be
introduced by a followup CL.

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.

8a277a790e MIPS: Eliminate intentional conversion from Smi to Int32 in HMul 
Port r16361 (b41ab14c)

Original commit message:
If not all uses of arithmetic binary operation can be truncated to Smi, check if they can be truncated to Int32 which could avoid minus zero check

Fixed DoMulI on X64 to adopt correct operand size when the representation is Smi

Fixed DoMulI on ARM. Constant right operand optimization is based on Integer 32 instead of its representation.
