Record allocation stack traces
...
This is initial implementation of allocation profiler.
Whenever new object allocation is reported to the HeapProfiler and allocation tracking is on we will capture current stack trace, add it to the collection of the allocation traces (a tree) and attribute the allocated size to the top JS function on the stack.
Format of serialized heap snapshot is extended to include information about recorded allocation stack traces.
This patch is r17301 plus a fix for the test crash in debug mode. The test crashed because we were traversing stack trace when just allocated object wasn't completely configured, in particular the map pointer was incorrect. Invalid Map pointer broke heap iteration required to find Code object for a given pc during stack traversal. The solution is to insert free space filler in the newly allocated block just before collecting stack trace.

Make Array.prototype.pop throw if the last element is not configurable.
...
Popping an element from an array should call [[Delete]] internal method
and pass true as the second argument (ECMA-262/5.1/#sec-15.4.4.6).
When the last element can't be deleted, throw a Type Error.
Not throwing the error would result in endless loop in the following test.
TEST=var a=[];Object.defineProperty(a,0,{});while(a.length)a.pop();
By the way fix another bug, or else i can't post any issues.
"presubmit.py" throw a "missing a correct copyright header" on windows.
Both the slash and the backslash are valid path separator on windows.

This will be used by DevTools so that we could generate a better preview in console. Namely, we could assume that a preview of an object is lossless if all its member functions are builtin.
We also may want to expose this to DevTools users via remote debugging protocol in Debugger.FunctionDetails struct.

The test started failing on V8 Linux - nosnap - debug after r17301 which added stack traversal to the allocation tracker. I'm disabling it for now until the problem is fixed.

Record allocation stack traces
...
This is initial implementation of allocation profiler.
Whenever new object allocation is reported to the HeapProfiler and allocation tracking is on we will capture current stack trace, add it to the collection of the allocation traces (a tree) and attribute the allocated size to the top JS function on the stack.
Format of serialized heap snapshot is extended to include information about recorded allocation stack traces.
