8494f3bf25 Improved function entry hook coverage 
Adds more coverage for function entry hook, sufficient to capture profiles that are contiguous from C++, through JS and back out to C++.

9e0f0a73dc Get rid of ZoneScope completely. 
There's no need to differentiate between an actual Zone and its
scope. Instead we bind the lifetime of the Zone memory to the
lifetime of the Zone itself, which is way easier to understand
than having to dig through the code looking for zone scopes.

Depends on https://codereview.chromium.org/17826004/

6d92511162 Reland "Remove IsInitialized checks from inlined API functions." 
The initialization sequence in Blink has been adapted to use explicit
isolate initialization instead of through calling v8::Null() as the
first API call.

48c16454b1 Revert "Remove IsInitialized checks from inlined API functions." 
This reverts r15277 due to failures in layout tests. Apparently Blink
still initializes the Isolate by calling v8::Null() as the first API
function on some paths.

f8db2414f2 Deprecate FACTORY helper macro. 
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.

Cygwin and Windows implementations are almost identical. Mac OS X uses different API to suspend thread but apart from that it is very similar to Windows implenenation.

53adf3b19c Add methods to allow resuming execution after calling TerminateExecution(). 
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::CancelTerminateExecution() -- When execution is terminated via a call
  to V8::TerminateExecution(), this method can be called to clear the
  termination exception so that the engine can continue to be used.

* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
  exception, HasTerminated() will return true to indicate it is valid to
  call V8::ResumeExecution() if desired.

A test case is added to cctest/test-thread-termination.cc.

9be937e6ed MIPS: fix NaN handling of Isolate::StackOverflow() 
The mjsunit/stack-traces-overflow.js test fails on MIPS target as Error.stackTraceLimit = NaN; should disable stack trace messages and Isolate::StackOverflow() assumes static_cast<int>(double NaN) < 0.

MIPS has a different NaN representation than other architectures so the NaN value casted to int is positive. This patch adds an isnan() check to make the handling of NaN uniform on all architectures.

61a2c53d09 Track Hydrogen statistics on a per-Isolate basis 
This is basically the same fix as the one for --trace-hydrogen, but now for
--hydrogen-stats. Removed a few train wrecks on the way.

0e3ed17ea4 Separate output files for --trace-hydrogen. 
The output filenames have now the form "hydrogen-<ProcessId>-<IsolateId>.cfg".
Minor cleanup on the way.

Note that we have a similar bug regarding statistics, but this will be handled
in a separate CL.

This includes:
- actually release handles kept by compilation info when compilation completes.
- do not use parallel recompilation on single core CPUs.
- artificially delay parallel recompilation for debugging.
- fix outdated assertions wrt optimization status.
- add "parallel" option to %OptimizeFunctionOnNextCall.

55f93b5532 Renamed "symbols" to "internalized strings" throughout the code base, 
in preparation of the introduction of ES6 'symbols' (aka private/unique names).

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.

The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).
