Supports growing non-COW JSArray by a single element if the backing store has room, and initial allocation of a backing store for the store to index zero of an empty array  to kPreallocatedArrayElements elements (e.g. the [] array literal).

fdf31d1bff Cleaned up DescriptorArray::CopyInsert a bit. 
The point of this refactoring is to remove some copy 'n' paste from the code,
preparing some upcoming changes related to CopyFrom and CALLBACKS with
transitions. The index fiddling is tricky enough to warrant a separate
refacoring-only CL...

function saved on the stack which wasn't used at all.

Some instructions can use >16 bit immediates if they represent a <=16 bit signed value.
However some logical instructions (andi, xori, ori, lui) should always treat the immediate value as unsigned.
This patch adds an ASSERT to these places and a minor change to MacroAssembler::li to satisfy this.

b8b50400d2 Inline builtin Math functions functions in more cases. 
Until now we only could inline as specialized HIR instructions when called
as a method (e.g. Math.abs)

It is very common practice to abbreviate calls to those functions by defining
a global or local variable like:

var a = Math.abs;
var x = a(123);

This change allows inlining them when called as a function (global or local).

dc3f16a321 I will apply it to the nodes that can't be mapped to Heap object or Native object. 
As example there are 'Detached DOM Tree' nodes in WebKit. It is very useful to be able to see all such
nodes grouped together. It can be done with help of some post processing but I did this explicitly
on v8 side because it is much faster. At the moment this kind of nodes has kNative type.
I'd like to hide these nodes from the Retainment View but I can filter them only by name.

b34e202b20 Removed IsTransitionType predicate. 
With the upcoming changes to CALLBACKS properties, a predicate on the transition
type alone doesn't make sense anymore: For CALLBACKS one has to look into the
property's value to decide, and there is even the possibility of having a an
accessor function *and* a transition in the same property.

I am not completely happy with some parts of this CL, because they contain
redundant code, but given the various representations we currently have for
property type/value pairs, I can see no easy way around that. Perhaps one can
improve this a bit in a different CL, the current diversity really, really hurts
productivity...

As a bonus, this CL includes a few minor things:

 * CaseClause::RecordTypeFeedback has been cleaned up and it handles the
   NULL_DESCRIPTOR case correctly now. Under some (very unlikely) circumstances,
   we previously missed some opportunities for monomorphic calls. In general, it
   is rather unfortunate that NULL_DESCRIPTOR "shines through", it is just a
   hack for the inability to remove a descriptor entry during GC, something
   callers shouldn't have to be aware of.

 * DescriptorArray::CopyInsert has been cleaned up a bit, preparing it for later
   CALLBACKS-related changes.

 * LookupResult::Print is now more informative for CONSTANT_TRANSITION.

0ec7773680 Allow bailing out of the register allocator when running out of virtual registers. 
1. Instead of checking upfront and estimating a limit for the number, we
now are able to stop register allocation and bailout when we don't
have enough virtual registers.

2. GCed some out-dated flags from flag-definition.h

3. Simplified the interface from the Lithium builder to the
register allocator in lithium-*.cc: For uses and definitions, we
just record the virtual register number given by the Hydrogen value id.
For temporaries, we request a new virtual register from the allocator.
For fixed temps, we don't need to do anything.

4. Increased number of deoptimization entries to 16K. Eventually we
probably want to make this array grow dynamically.

87ccb1d740 Break a circular include dependency. 
1. heap-inl.h has a function Heap::_inline_get_heap_ that calls
Isolate::Current() defined in isolate.h, so heap-inl.h requires
isolate.h.

2. Isolate has an embedded Heap member, so isolate.h requires heap.h.

3. heap.h has inline functions functions defined that call
Heap::_inline_get_heap_, so heap.h requires heap-inl.h (!).

The upshot is that all three need to be included wherever one is.  A
simpler way is to break the cycle by moving the inlined functions in
heap.h to heap-inl.h.

07d720ec41 Detailed heap snapshot usability improvement. 
The detailed heap snapshot has two groups of nodes. The first one
is the group for v8 heap nodes and the second one is the group for
native objects. At the moment we have two different sets of native
objects. There are 'Detached DOM trees' and 'Document DOM trees' type of objects.

I think it'd be nice to replace one group containing all native objects with
separate groups for different types of native objects.

This simple refactoring makes it very clear that clearing non-live transitions
actually consists of 2 quite separate things. Things would even be nicer if the
prototype transitions were represented by a separate data structure instead of
reusing FixedArray in an interesting way once again.

As an additional bonus, this CL makes it possible to read each of the methods in
question on a 30" screen without scrolling!

6859247172 Do not follow accessor map transitions when marking descriptor arrays. 
Note that we currently have no such transitions, but we will in the future, and
we have to avoid keeping maps live too long.

891f0efa3f Handle map transitions in CALLBACKS when doing map tree traversal. 
We will have such transitions in the future and this CL is necessary to keep
slack tracking working then.

0b3ce1dd9e Remove unnecessary IGNORE policy from Lithium operands. 
1. This policy was only used for unused spill operands. I'm assigning
an INVALID LOperand to those instead. As a result, we only need
3 bits to encode the policy and have one more available for virtual
registers.

2. Furthermore, corrected the calculation of the maximal number of virtual
registers and changed the upper limit for the size of the Hydrogen IR
accordingly.

3. Doubled the maximal number of deoptimization entries to 8K.

83b439a0f9 Further robustify the keyed lookup cache against unlucky hash 
seeds.  This change is performance neutral on most snapshot
VM builds, but provides a big improvement on string-fasta
on around 5% of builds.
