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).

We cannot use chdir to set the working directory on a per-isolate basis,
hence we need to specify absolute directories instead for this test to
work properly on multi-threaded runs.

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.

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.

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.
