0eb4dea12d Implemented "no heap access" mode for JSFrame which is used for stack sampling in profiler.
As I discovered that JSFrame accesses SharedFunctionInfo only to calculate caller SP and the latter is not used in profiler's stack sampling, I disabled accessing heap objects in JSFrame when doing stack sampling. This finally made V8's profiling stable when used from Chrome on a real web app.

8ce3aae482 Workaround for http://crbug.com/9746:
- 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.

835b89b727 Fixed step in handling for function.call.
For function.call debug step in did not work as execution did not break in the function called. This has now been fixed using the same means as for function.apply in CL http://codereview.chromium.org/63055.

a74fcf458c Fixed the step in handling for function.apply.
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.

35d6c8fb03 Remove ENTER_V8 from small API functions that do not need access to
V8's heap or only need read access.

This means that IsDeadCeck and EnsureInitialized could sometimes be
called without having already entered the VM.  To simplify things,
this is made always the case.  A couple of error callbacks do not need
to leave V8 because they haven't entered.

Consistently enter V8 after LOG_API (since LOG_API is sometimes before
EnsureInitialized or IsDeadCheck).

This all should have no effect unless V8 is built with
ENABLE_HEAP_PROTECTION and run with --protect-heap.

aacd90314f Reland exception propagation fix.
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.

1f7a7d9c58 Change handling of debugger unloading.
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.

8b7a288e48 Debugger message handler can be called from V8 thread.
The message handler function set through the debugger API is normally called in a different thread than the V8 thread where execution is stopped due to debugger event. This change adds an option to the API for specifying that the message handler should be called directly from the V8 thread. For an application like Chrome where thread dispatching is already in place this makes more sense.

Add an option to the message handler debugger API to process messages in the thread where V8 is running instead of posting it to a queue for processing on a additional thread.

9142c42df2 Fixed a bunch of memory leaks in tests, including:
- 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.

03419c8369 Simplify the way the code generator handles calls to IC stubs. Before
we dispatched on the IC stub kind in a generic CallCodeObject
function.  Now, we have special functions for the load and store IC
stubs.

We also (for the load and store ICs) handle moving register arguments
into place only after the stack is prepared for the call.  This
replaces some memory-to-memory moves (for copies whose backing store
is occupied by a register needed for the arguments) with
memory-to-register moves.

32de098ef6 Allow the debugger agent to reuse ports stuck in TIME_WAIT for listening.
When the debugger agent terminates the used port can be stuck in TIME_WAIT for some time depending on the OS and the state of the socket. With this change will allow the debug agent to start listening on a port still in TIME_WAIT. During development of both V8 and embedding applications this makes it much easier to restart an application using the debugger agent.

This also makes it possible to run the tests involving the debugger agent multiple times without failure.

8dffcb9efa Flush ICs when adding setters to an object or setting a __proto__ to
an object that holds a setter.  If there are no store ics then no
flushing is done.  The implementation has been tweaked so that no ICs
are cleared during normal context creation.
This may cost us some performance but I'm submitting it as it is and
if there are problems we can either decide to be smarter about when,
what and/or how we clear, or back this change out altogether.

17b498c957 A new stack guard break flag DEBUGCOMMAND has been introduced. This is used to signal debug break due to debugger commands available in the queue for processing. If a stack guard break happens with this flag and not the DEBUGBREAK flag the no debug break event is generated and execution is resumed automatically when all debugger commands in the queue has been processed.
This makes it possible to remote debuggers to just add commands to the queue without having to request a break as well. As soon as any JavaScript executes the debugger commands will be processed and the response send to the remote debugger.

Currently hide this behind a flag (--debugger-auto-break) as the current command line debugger in Chrome is not designed for this new behaviour, whereas the new Chrome developer tools will use it.

79aae815dd During the refactoring in r1461 and adding of script ids in r1468 the propagation of a boolean flag was missing. This caused the line numbers retreived through ScriptMirror objects to ignore the resource line offset information in the script.
Added an explicit false parameter where the parameter was previously left out.

Added a test case for this.

c7f2458912 Tweak an assertion in the jump target destructor so that it only
applies to initialized jump targets, and not in the case of a stack
overflow.

04cc9cfffd Revert the exception propagation fix. It leads to crashes because
Top::external_caught_exception_ and Top::try_catch_handler_ are no
longer in sync.  Pulling it out until I have the time to fix it.
