6ab7a23f6c Object.observe: use JSWeakMaps instead of raw ObjectHashTables in observation state 
object-observe.js uses weak maps to add "hidden" properties to
objects. Previously, the hash tables it was using weren't actually
weak. This patch changes the existing runtime functions to create
instances of JSWeakMap instead of exposing ObjectHashTable directly.

0c3575c874 Generate the TransitionElementsStub using Crankshaft 
This includes:
* Adding support for saving callee-clobbered double registers in Crankshaft code.
* Adding a new "HTrapAllocationMemento" hydrogen instruction to handle AllocationSiteInfo data in crankshafted stubs.
* Adding a new "HAllocate" hydrogen instruction that can allocate raw memory from the GC in crankshafted code.
* Support for manipulation of the hole in HChange instructions for Crankshafted stubs.
* Utility routines to manually build loops and if statements containing hydrogen code.

1c1fdc7da2 Better fix for MemoryChunk::owner(). 
Pointer arithmetic such as "owner_ - kFailureTag" is undefined behaviour
unless owner_ points to a valid object.

This allowed Clang to assume the subtraction would never be NULL,
causing problems in the caller (see https://codereview.chromium.org/12090072/).

To fix this, we should cast owner_ to intptr_t before doing the
arithmetic.

672056ac88 Only mark the descriptor that is valid for the map in question. If this map 
transitioned from a map with a different descriptor array (or has no back
pointer), mark all valid descriptors from the start.

This fixes the following memory leak: Map A shares a descriptor array
with map B. Map B adds constant function c that in its scope holds on to
an instance of B. If the descriptor array of A would keep all the shared
descriptors alive, including c, this keeps alive both A and c
indefinitely.

This CL also fixes a bug in descriptor array trimming. When trimming
descriptor arrays we need to trim off the slack as well (thus the entire
storage); and since we are trimming a descriptor array, we need to trim
* kDescriptorSize.

c001d928df Object.observe: don't unnecessarily emit oldValue for reconfigurations of data properties 
When a data property has its attributes changed but its value remains the same,
don't emit an oldValue. This makes the API more consistent by only emitting
oldValue when the value of a property has actually changed (or been removed,
in the case of a reconfiguration as an accessor property or a deletion).

e7420f65bc Also allow the empty object map to keep transitions. 
With the old implementation, due to the map-check being inadequate, such
transitions were already added for cross-context field stores. It is not
necessary anymore to not store transitions, since we properly clear
non-live transitions. Globally enabling this feature will help find more
bugs.

9cec21e60c profiler: log solib addresses unconditionally 
Make --prof_lazy log the addresses of shared libraries. Without those addresses,
the output of the tick processor is not very useful for node.js applications.

Address logging was disabled for --prof-lazy in r3154 for reasons that no longer
apply: the profiler is started on demand and hence looking up the addresses is
deferred until it's actually necessary.
