As we'll have several aspects of heap profiling, it is more handy to control them using binary flags than by individual functions. CPU profiling represent just a particular aspect to control, so {Pause,Resume}Profiler and IsProfilerPaused are only left for compatibility.

For now, PROFILER_FLAG_HEAP_STATS and PROFILER_FLAG_JS_CONSTRUCTOR are equivalent, but later will be split.

It is activated with '--log-gc' flag.

JS object size is calculated as its size + size of 'properties' and 'elements' arrays, if they are non-empty. This doesn't take maps, strings, heap numbers, and other shared objects into account.

As Soeren suggested, I've moved ZoneSplayTree from jsregexp to zone, and removed now empty jsregexp-inl header file.

I found two causes of flakinness:
 - SIGPROF signal isn't delivered to a process;
 - Profiler thread (the one that retrieves tick events from
   the queue and writes to log) doesn't get a CPU;
Both are fixed.

The script from bug description with run count increased to 200 runs without any test failures.

OS X and Windows are unaffected because they don't use signals mechanism.

Debugger should not stop in its own code and in code of built-in functions since it may confuse user.Debug break handler checks whether current function is a built-in or a debugger one and just resumes execution if it is.

CallCheckStackGuardState is no longer called in loop in the RegExp code as it hangs if debug break flag is not reset after calling Execution::HandleStackGuardInterrupt.
