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.

instead of direct_dependent_settings - with V8 headers
being included in other headers, the former works much better.

This is a configuration that is not used for Google Chrome
neither V8 buildbot, and has been tested for its intended
use case (Linux distributions).

090d09d685 ES6 symbols: Implement Symbol intrinsic and basic functionality 
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.

Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).

1074e1f558 Fix the xrange calculation of the V8 timeline plot 
Currently an xrange is calculated by V8.Execution. This would be fine for JavaScript benchmarks in which everything happens inside of V8.Execution. On the other hand, in Chrome profiling, events can happen outside of V8.Execution. To visualize such outside events, we need to calculate an xrange so that the xrange covers all events.
