3003b2156b Basic GDB JIT Interface integration. 
It has certain overheads even when gdb is not attached so it is guarded by ENABLE_GDBJIT_INTERFACE define and --gdbjit flag.

57e072298f Merge math function ids and custom call generator ids. 
Two old id types are replaced by builtin function ids. We can use
these in the code generators to emit custom code for the selected
functions.

8f22667805 Provide more functions to CPU profiler (fix issue 858). 
The cause for missing functions is that some of them are created
from compiled code (see FastNewClosureStub), and thus not get
registered in profiler's code map.

My solution is to hook on GC visitor to provide JS functions
addresses to profiler, only if it is enabled.

6bd9d953dd Reapplying r5147 (caching maps for slow case objects). 
r5147 wrongly assumed that a code cache for a slow case map is always empty.
This patch solves this: whenever we attempt to add a stub to a map's code cache 
we check that this map is cached. If it is we give the object its own copy
of the map and only then modify the map.

afc15bb48f Reapply load ICs for nonexistent properties. 
We need to be careful to check global property cells for the property
encountered during lookup.  Therefore, the ICs have to be specific to
the name of the property if global objects are involved.  In
principle, this means that we could get a large number of monomorphic
ICs for the same map if there is a global object in the prototype
chain.  However, since this is only done for normal load ICs and not
for keyed load ICs I do not expect this to be a problem.  I will
experiment with it once this goes in.

0672938b88 Fix a crash caused by garbage collection during generation of a 
callback load (or keyed load) IC.

The problem was that the IC code calls a stub, which can allocate and
thus trigger a GC if the stub is not already generated.  Problem is
solved by adding the ability to "try" to call a stub, trying to
generate the stub code if necessary but signaling an allocation
failure if generating the code is not possible.

callbacks to be called directly from native code.

4339205dd2 Add code creation logging for construct stubs. 
Otherwise, tick processor reports unknown code deletes / moves for them.

717394492d Generate specialized constructor code for constructing simple objects. 
For objects which only have simple assignments of the form this.x = ...; a
specialized constructor stub is now generated. This generated code allocates the
object and fills in the initial properties directly. If this fails for some
reason code continues in the generic constructor stub which in turn might pass
control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change.
For x64 and ARM the generic construct stub is used.

This is change is identical to http://codereview.chromium.org/174392 (committed in r2753 and reverted in r2754) except that a few parts have already been committed from http://codereview.chromium.org/173469 (committed in r2762).
