a6a8455fdb Revert "This patch implements optimized objectInfo structure which manages the set of observers associated with an object and the changeRecord types which they accept." 
This reverts r16539 as it triggers crashes on the GC stress bot.

b26d28d964 This patch implements optimized objectInfo structure which manages the set of observers associated with an object and the changeRecord types which they accept. 
Observation in the normal case (Object.observe, default accept types, one observer) now allocates fewer objects and unobservation no longer needs to scan and splice an InternalArray -- making the combined speed of observe/unobserve about 200% faster.

This patch implements the following optimizations:

-objectInfo is initially created without any connected objects or arrays. The first observer is referenced directly by objectInfo, and when a second observer is added, changeObservers converts to a mapping of callbackPriority->observer, which allows for constant time registration/de-registration.

-observer.accept and objectInfo.performing are conceptually the same data-structure. This is now directly represented as an abstract "TypeMap" which can later be optimized to be a smi in common cases, (e.g:   https://codereview.chromium.org/19269007/).

-objectInfo observers are only represented by an object with an accept typeMap if the set of accept types is non-default

35490d82a9 Add OptimizedCodeList and DeoptimizedCodeList to native contexts. Both lists are weak. This makes it possible to find optimized code that is not referred to by any function, but still needs to be deoptimized. It obsoletes the weak deoptimizing code list in the deoptimizer data and generally simplifies the process of deoptimizing code.

281de965a4 Import ConditionVariable class. 
Condition variables are synchronization primitives that can be used
to block one or more threads while waiting for condition to become
true.

Right now we have only semaphores, mutexes and atomic operations for
synchronization, which results in quite complex solutions where an
implementation using condition variables and mutexes would be straight
forward.

There's also a performance benefit to condition variables and mutexes
vs semaphores, especially on Windows, where semaphores are kernel
objects, while mutexes are implemented as fast critical sections,
it CAN be beneficial performance-wise to use condition variables
instead of semaphores.

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.

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.

22b70b0508 Add OptimizedCodeEntry as a new heap object type. An optimized code entry represents an association between the native context, a function, optimized code, and the literals. Such associations are needed by the deoptimizer and optimized code cache to efficiently find related optimized code and functions for a given context or shared function info.

adab11d0f9 Revert "Cross-compiling from Linux to Android requires -lrt for the host toolset.", "Fix Visual Studio debug build after r16398." and "Reland "Add Chromium-style TimeDelta, Time and TimeTicks classes, and a new ElapsedTimer class."" 
This reverts commit r16398, r16399 and r16402 for breaking the Windows
WebKit tests. Will reland fix which doesn't use High Resolution Timer
for ElapsedTimer (we suspect QueryPerformanceCounter overhead is
responsible for test breakage).
