bf42ded40d 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

The test has been marked as intermittently failing since 2011 and since that "code-creation" event signature has changed a bit. I updated the parser in the test but that revealed another issue: "code-creation" events with type 'Script' didn't match functions with type 'LazyCompile' retrieved during the heap traversal because the later had name " :1:1" which didn't match the script's name.

5768fcf12c Fix the CPU feature detection. 
Move all of the CPU detection logic to the CPU class, and make
all other code use the CPU class for feature detection.

This also fixes the ARM CPU feature detection logic, which was
based on fragile string search in /proc/cpuinfo. Now we use
ELF hwcaps if available, falling back to sane(!!) parsing of
/proc/cpuinfo for CPU features.

The ia32 and x64 code was also cleaned up to make it usable
outside the assembler.

4db1f475ec Support higher CPU profiler sampling rate on posix systems 
New flag is added that allows to specify CPU profiler sampling rate in microseconds as command line argument. It was tested to work fine with 100us interval(currently it is 1ms). Default values are kept the same as in the current implementation. The new implementation is enabled only on POSIX platforms which use signals to collect samples. Other platforms that pause thread being sampled are to follow.

SIGPROF signals are now sent on the profiler event processor thread to make sure that the processing thread does fall far behind the sampling.

The patch is based on the previous one that was rolled out in r13851. The main difference is that the circular queue is not modified for now.

On Linux sampling for CPU profiler is initiated on the profiler event processor thread, other platforms to follow.

CPU profiler continues to use SamplingCircularQueue, we will probably replace it with a single sample buffer when Mac and Win ports support profiling on the event processing thread.

When --prof option is specified profiling is initiated either on the profiler event processor thread if CPU profiler is on or on the SignalSender thread as it used to be if no CPU profiles are being collected.

ProfilerEventsProcessor::ProcessEventsAndDoSample now waits in a tight loop, processing collected samples until sampling interval expires. To save CPU resources I'm planning to change that to use nanosleep as only one sample is expected in the queue at any point.

140ebd974e Fix crashes of some CPU profiler tests on Windows after r16284 
All the tests that started crashing create ProfilerEventsProcessor on the stack. After r16284 SamplingCircularQueue buffer is allocated as a field of the queue instead of separate heap object. This increased self size of ProfilerEventsProcessor by about 1Mb. Windows malloc fails to allocate such an object on the stack and crashes.

30375b0937 Promote ArrayBuffer, DataView and typed arrays to non-experimental. 
The primary reason for this change is to bake these guys into the
snapshot.

Flag definitions (--harmony-typed-arrays, --harmony-array-buffer) are
still there so that Blink does not complain, but they are noop and
default to true.

85d8178d87 Deprecate self and total time getters and total sample count getter on CpuProfileNode 
All of these values are derived from the self samples count and there is no need to evaluate them in v8 when clients can do that when needed on their side.

Also added unsigned GetHitCount() which should be used instead of double GetSelfSamplesCount(). I'm going to deprecate the latter one once Blink has switched to GetHitCount.

707fdd4c6a Support idle time in CPU profiler 
This change provides an API for the embedder to tell CPU profiler if it is idle or busy with some task. This way we can discriminate between idle time and some native code execution.

8fb95efdda Improve internal stringifcation for custom Error objects. 
If an developer attempts to "subclass" Error by running
`MyError.prototype = new Error();`, then the internal v8::Message object
that's produced and handed off to `window.onerror` handlers is poorly
stringified as "[object Object]".

This patch adjusts the stringification process for these objects to
include not only native Error objects, but also objects that have Error
in their prototype chain, and haven't overwritten Error.toString with
some custom variant.
