9dcf002f31 Fix filtering of store buffer for large object pages. 
Our Heap::FreeQueuedChunks generates fake inner chunks in large object
pages queued for freeing, so that StoreBuffer::Filter can recognize them
as pages to be freed. This also relies on MemoryChunk::Contains to work
properly, which is why the size field needs to be initialized as well.

e24c612a5e Fix setting array length to be ES5 conform. 
This also refactors the way we set the length of an arrays' backing
store to use the new elements accessor interface. The actual fix is in
DictionaryElementsAccessor::SetLengthWithoutNormalize() where we first
search for non-deletable elements according to ES5 section 15.4.5.2
specifications.

Snippet from the specification: Attempting to set the length property of
an Array object to a value that is numerically less than or equal to the
largest numeric property name of an existing array indexed non-deletable
property of the array will result in the length being set to a numeric
value that is one greater than that largest numeric property name.

e8bccc2cb0 Block scoped const variables. 
This implements block scoped 'const' declared variables in harmony mode. They
have a temporal dead zone semantics similar to 'let' bindings, i.e. accessing
uninitialized 'const' bindings in throws a ReferenceError.

As for 'let' bindings, the semantics of 'const' bindings in global scope is not
correctly implemented yet. Furthermore assignments to 'const's are silently
ignored. Another CL will introduce treatment of those assignments as early
errors.

This change is based on my previous change enabling inlining calls-as-function
fixing the bugs related to deoptimization.

The function value on top of the environment was dropped too late in the old code.
As a result we could get a wrong value on top after deoptimization.

This change includes r9619. It was reverted because of test failures that are fixed
with this patch.

This time, we initially leave the HTypeof instruction in the Hydrogen graph,
even for the special cases. We later try to remove this instruction (and any
HConstant) in the canonicalization pass, if possible. Always removing the
HTypeof during the initial graph construction is wrong if e.g. it is used in an
HSimulate.

The removals can be generalized a bit, but this will happen in a separate CL.

de7b222e36 Support for precise stepping in functions compiled before debugging was started (step 2) 
This change will ensure that full code with debug break slots is compiled and activated for all functions which already have activation frames.

This additional handling is only for functions which have activations on the stack, and that activation is of the full code compiled without debug break slots. In that case the full code is recompiled with debug break slots. It is ensured that the full code is compiled generating the exact same instructions - except for the additional debug break slots - as before. The return address on the stack is then patched to continue execution in the new code.

Also fixed SortedListBSearch to actually use the passed comparision function.

16ae2551ae Search prototypes for accessor setters if interceptor returns empty value. 
Extract the part of SetPropertyForResult that searches the prototype chain
for accessor setters into a separate function SetPropertyInPrototypes.
Call this function in SetPropertyPostInterceptor.

This should fix both optimized and unoptimized cases because
the cache stub for storing with interceptor calls the runtime system.

This allows getting a heap object by a heap snapshot node for further
inspection. Very useful for objects from bindings that mostly have
getter-provided fields.

bfd048173f Notify collector about lazily deoptimized code objects. 
All slots that were recorded on these objects during incremental marking should be ignored as they are no longer valid.

To filter such invalidated slots out during slots buffers iteration we set all markbits under the invalidated code object to 1 after the code space was swept and before slots buffers are processed.
