For keyed IC loads setting a break point now ensures that the inlined code is not used. When the break point is set the inlined map check is changed to fail causing the inlined code not to be used but the IC to be called. As long at the break point is set the map check will stay invalid.

numerical order independently of the representation of the object.
Exchanged the order of enumeration of integer and string keys so
integer keys are first instead of string keys to better match
WebKit/JSC behavior.
Added test cases that document our enumeration order choice.

This is the first step in reimplementing tick processing scripts in
JavaScript. The goal is to have the same source both for Dev Tools and
Golem, so Python implementation will be removed to avoid code
duplication.
The implementation follows the Dev Tools style: namespaces and JSDocs
are used.

Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.
For examples of cases where function names can be inferred, see the tests file.

- Added special cutouts if a Vector has NULL data, which will now happen
if an external string's resource has been deleted.
- Added an verification phase before old gen GC to verify that all real
entries in the SymbolTable are valid symbols.
- Added test that verifies the correct behaviour of the workaround.

The generic step-in mechanism floods the function called with break points to ensure a break is hit when entering the function. This generic mechanism was also used for function.apply. The code for function.apply contains a keyed load IC which was patched when stepping into function.apply. However function.apply enteres an internal frame not a JavaScript frame. This caused the logic for returning from the break in function.apply to fail as it forced a jump to the IC on the top JavaScript frame. The top JavaScript frame was the frame for the function calling function.apply not the frame for the apply function. Now returning from the break point in the keyed load IC in the apply code caused a jump to the code for the call IC for the function calling function.apply in the first place. Not a pretty sight.
Step-in now handles function.apply as a separate case where the actual JavaScript function called through apply is flodded with breakpoints instead of the function.apply function.

Fix exception propagation problem where undefined was returned instead
of an empty handle in case of an exception. This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.
The issue is that exceptions are not rescheduled if they are
externally caught. Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.
A couple of tests will fail on the ARM simulator because the simulator
has separate stacks for C++ and JavaScript. I have marked the tests
as failing only on the simulator.

* Remove the non-working methods from the os object on d8 on Windows
so you can test for their presence with if (os.system).
* Add a test (not run by default since it only works on d8).
* Fix incorrect use of wait that left defunct processes (zombies).

Add a semaphore for accessing debugger varaibles which can be changed from a different thread. This is mainly the debug message handler which can be set to NULL to disconnect the debugger.
Control the unloading of the debugger from the V8 thread. Before the debugger unload was called from the thread setting the debug message handler to NULL. This was not safe as this involves calling into V8. This change handles the unloading of the debugger either when entering a debugger event and the debugger was disconnected while the debugger was not active or when leaving the debugger and the debugger was disconnected while the debugger was active.
Add a flag to avoid unloading the debugger if debugger code is used by the application for other purposes than debugging.
Added tests for clearing the debug message handler.

- String traversal test data (now in a zone)
- Debug message thread (now joined on exit)
- Threading test threads (now joined on exit)
- Changed message tests framework to cope with valgrind
Also, fixed a bug where we'd try to delete stack-allocated objects
when tearing down v8. Good times.
