c7b1b79e4d This is the exact copy of r17365 which was reverted in r17488 due to memory corruption. The root cause for the memory corruption - missing check for bump pointer limit before storing filler map must be addressed in r17626 where allocation hooks were removed from the generated code and left only in the runtime. 
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.

3cf157b43b Inline zero argument array constructor. 
patch from issue 54583003 (dependent code).

Zero arguments - very easy

1 argument - three special cases:
  a) If length is a constant in valid array length range,
     no need to check it at runtime.
  b) respect DoNotInline feedback on the AllocationSite for
     cases that the argument is not a smi or is an integer
     with a length that should create a dictionary.
  c) if kind feedback is non-holey, and length is non-constant,
     we'd have to generate a lot of code to be correct.
     Don't inline this case.

N arguments - one special case:
  a) If a deopt ever occurs because an input argument isn't
     compatible with the elements kind, then set the
     DoNotInline flag.

cec8383cff Provide private symbols through internal APIs 
Adds a notion of private symbols, mainly intended for internal use, especially, self-hosting of built-in types that would otherwise require new C++ classes.

On the JS side (i.e., in built-ins), private properties can be created and accessed through a set of macros:

  NEW_PRIVATE(print_name)
  HAS_PRIVATE(obj, sym)
  GET_PRIVATE(obj, sym)
  SET_PRIVATE(obj, sym, val)
  DELETE_PRIVATE(obj, sym)

In the V8 API, they are accessible via a new class Private, and respective HasPrivate/Get/Private/SetPrivate/DeletePrivate methods on calss Object.

These APIs are designed and restricted such that their implementation can later be replaced by whatever ES7+ will officially provide.

bc4ad49b25 Do not add values to HGraph in Lithium. 
Lithium uses indexes after the maximium value ID in the HGraph as indexes
of virtual registers and assumes that the maximum value ID does not change.

The IsStandardConstant and GetConstantXX functions could add constants to
HGraph, which aliased virtual registers with real values. This could confuse
the register allocator to think that a value in a virtual register is tagged
and to incorrectly set it in the pointer map.

cec8548d0e Correct handling of arrays with callbacks in the prototype chain. 
Our generic KeyedStoreIC doesn't handle the case when a callback is
set on array elements in the prototype chain of the object, nor do
we recognize that we need to avoid the monomorphic case if these
callbacks exist.

This CL addresses the issue by looking for dictionary elements in
the prototype chain on IC misses and crankshaft element store
instructions. When found, the generic IC is used. The generic IC is
changed to go to the runtime in this case too.

In general, keyed loads are immune from this problem because they
won't return the hole: discovery of the hole goes to the runtime where
the callback will be found in the prototype chain. Double array loads
in crankshaft can return the hole but only if the prototype chain is
unaltered (we will catch such alterations).

Includes the following patch as well (already reviewed by bmeurer):
Performance regression found in test regress-2185-2.js. The problem was
that the bailout method for TransitionAndStoreStub was not performing
the appropriate transition.

980739a29c Improve implementation of HSeqStringSetChar. 
This improves the generated code for HSeqStringSetChar across
all platforms, taking advantage of constant operands whenever
possible. It also drops the unused DefineSameAsFirst constraint
for the register allocator on x64 and ia32, where it caused
unnecessary spills when the string operand was live across the
HSeqStringSetChar instruction.

A new GVN flag StringChars is introduced to express dependencies
between HSeqStringSetChar, HStringCharCodeAt and the upcoming
HSeqStringGetChar (the GVNFlags type is now 64bit in size).

Also improves the test case.

b8660f2091 Revert "Record allocation stack traces". 
This reverts commit r17365 for memory corruption. The issues
are most probably related to storing a filler map without
checking the bump pointer first, and traversing the stack
when called from within a stub (or builtin), while the code
assumes that it's called from a JS function.

a083601e73 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.

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.

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.

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.

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)

Linux:
