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.

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.

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.

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.
