e25920da19 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.

bdeaf7514a Enable preaging of code objects when --optimize-for-size. 
This change means that code which is never executed is garbage collected immediately, and code which is only executed once is collected more quickly (limiting heap growth), however, code which is re-executed is  reset to the young age, thus being kept around for the same number of GC generations as currently.

ignoring all memory accesses from V8), but don't help testing V8 itself in any

In the process:
- Add a command-line flag --opt-code-positions to track source position information throughout optimized code.
- Add a subclass of the hydrogen graph builder to ensure that the source position is properly set on the graph builder for all generated hydrogen code.
- Overhaul handling of source positions in hydrogen to ensure they are passed through to generated code consistently and in most cases transparently.

Port r17290 (b5fabb92)

6b840f563e Temporarily disable test-heap-profiler/TrackHeapAllocations 
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.

66bb9d1563 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.

19b2ee1c40 Handlify PropertyCell::SetValueInferType and friends. 
This finally gets rid of the pesky trampoline in SetValueInferType and
enforces the layering between PropertyCell and Heap. It requires full
handlification of NewGlobalObject as well, which is only used when the
snapshot is created at compile-time.
