1a9997ee37 Make v8 compilable without V8_USE_UNSAFE_HANDLES. 
Without this modification, we get this error: "dereferencing type-punned pointer
will break strict-aliasing rules" (GCC strict aliasing).

Also included small CcTest sanity fixes: isolate() cannot return anything else
than default_isolate().

061f523b5a Change cctest/test-lockers to not copy persistent handles around. 
Instead, create Local handles to pass them around. This also means that the
code needs to be shifted around a bit such that a handle scope exists when
creating threads.

5206b08451 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.

dc72037e10 ES6 symbols: extend V8 API to support symbols 
Specifically:
- Introduce Symbol and SymbolObject classes.
- Generalise Object::Has and Object::Delete to arbitrary Value-typed keys.
- Generalise some places in the API implementation from String to Name.

It is not possible to intercept symbol-named properties. That is consistent with the idea that symbols are private and should not leak.

c7ce87f865 Add sanity test for CPU profiler 
The new test checks full CPU profiling cycle: using public
V8 API it starts profiling, executes a script, stops profiling
and analyzes collected profile to check that its top-down
tree has expected strutcture. The script that is being profiled
is guaranteed to run > 200ms to make sure enough samples
are collected.

To avoid possible flakiness due to non-deterministic time required
to start new thread on varios OSs when Sampler and ProfilerEventsProcessor
threads are being started the main thread is blocked until the threads
are running.

Also I removed the heuristic in profile-generator.cc where we try
to figure out if the value on top of the sampled stack is return address
of some frameless stub invocation. The code periodically gives false positive
with the new test ending up in an extra node in the collected cpu profile.
After discussion with jkummerow@ we concluded that the logic is too fragile
and that we can address frameless stub invocations in a more reliable way
later should they have a noticeable effect on cpu profiling.

a22790bfed Change Context::New to not create persistent handles. 
This moves the responsibility of putting a new context into a persistent
handle to the embedder. Also it removes one API function where the copy
constructor for persistent handles is needed.
