19d716989e Unify handling of position info in AST, part 1 
* AstNode now has a position info.
* Removed various ad-hoc position infos from subclasses (most of which had it).
* Position is always set with the constructor, instead of later.
* Take care to use kNoPosition in the right spots, to not crash the debugger.

Still to do:

* Eliminate Conditional::then/else_position and WhileStatement::condition_position.
* Make CaseClause a proper AstNode and eliminate its custom position.
* If possible, eliminate all uses of kNoPosition.

Reverting reverted r17148 and fixing build (test) breakage by side stepping the Windows vs. Linux issue of different Date object for the same millisecond time stamp.
We do that by using UTC Date methods (they eliminate DST problems).

Windows:
new Date(129193200000);
Sun Feb 03 1974 23:00:00 GMT-0800 (Pacific Standard Time)

3228e953f9 Unflake cctest/test-cpu-profiler/JsNativeJsRuntimeJsSample on Win32 Debug 
Profiler is now started from JavaScript. Since we always capture stack trace when starting profiler there should always be at least one expected sample in the profile.

Also changed ProfilerEventsProcessor::AddCurrentStack to make sure it call TickSample::Init to instead of custom initialization code.
