cf3c1a8c18 Arrays created with new Array(n) are not assumed to be sparse unless the given 
size is truly huge.  A test had to be modified slightly so as not to be too slow.

c013397399 Adding support for reporting addresses of JIT compiled code to OProfile. 
Please be warned that current gHardy versions have OProfile 0.9.3
which doesn't have JIT API. You need to install OProfile 0.9.4
with a 32-bit version of opagent library. Instructions are on the
internal Wiki page: http://wiki/Main/V8UsingOProfile

e37f6087c6 In List::Add, correctly handle the case of adding a reference to a 
preexisting list element to a list, and to not return anything (we
never used the return value).  Remove List::Insert, it is not
currently used or needed.  Change List::AddBlock to take a copy of
the element to be replicated rather than a reference.

567d9a603e Tweak the context disposal GC heuristic: If the garbage collector 
interface is exposed through the global gc() function, we avoid 
being clever about forcing GCs when contexts are disposed and leave 
it to the embedder to make informed decisions about when to force 
a collection.

6ef7ef657e Add remote debugging front end to developer shell. 
D8 now supports demote debuggign of a V8 instance with the debugger agent enabled. Running D8 with the option --remote-debugger will try to connect to a V8 debugger agent and process the debugging protocol. The command line UI is the same as for the D8 in-process debugger as the same code is used for processing the debugger JSON.

92aa4ab36c Add V8 debugger agent. 
The debugger agent listens on a TCP/IP port for a remote debugger connection. When such a connection is established the debuger JSON protocol is communicated between the agent the the remote debugger. The messages containing the JSON protocol has a RFC-822 like header with a Content-Length field and with the body containing the JSON in UTF-8 encoding.

The D8 shell has option --debugger-agent to start the debugger agent.

3db607a3c4 Dump more stack frames to perf log when executing a C++ function. 
JavaScriptFrameIterator is templatized on the iterator type and renamed to JavaScriptFrameIteratorTemp.
The original JSFI is now a typedef for JavaScriptFrameIteratorTemp<StackFrameIterator>. Because of templatizing, JSFI code is moved to frames-inl.h

StackTraceFrameIterator moved to frames.*

Implemented SafeStackFrameIterator which wraps StackFrameIterator and have the same interface. It performs additional checks of stack addresses prior to delegating to StackFrameIterator. SafeSFI is used in an another specialization of JavaScriptFrameIteratorTemp template to perform safe JS frames iteration on sampler ticks.

I haven't took an advantage of having multiple stack frames in tickprocessor yet.

be059966c1 Add socket support to platform code. 
The new Socket class is an encapsulation of the standard BSD socket API. As it depends on platform specific include files and have some slight platform variations it is part of the platform code.

On Mac OS only the option SO_REUSEADDR is set to true for server sockets. Running the test required it as the bound listener socket would sometimes end up in TIME_WAIT. On Windows and Linux this has never been observed (given the client end of the socket is closed before the server end).

The code has been tested on Windows, Linux and Mac OS. The FreeBSD version is a copy of the Linux version but has not been compiled nor tested.

Missing Xcode project updates.

0c7af39737 Speed up access to global variables from eval scopes. Traverse the 
surrounding context to figure out if the variable could be global.  If
the variable could be global we check context extension objects at
runtime and use a global LoadIC if no variables have been introduced
by eval.

Fix crash bug when loading function arguments from inside eval.  The 
shadowed variable in the DYNAMIC_LOCAL case does not rewrite to a slot in 
that case.

b6a1cd6787 Simplify non-smi bit operation optimization. The explicit range 
checks are not needed.  If we fail to store the float as a 64-bit
integer, we just go to the runtime system.  The only extra case in
which we enter the runtime system is for NaN which should not matter.

44b83d3e77 Add host callback for debug break. 
Add the ability to have the host embedding V8 receive a callback in the V8 thread while V8 is processing a debug callback. When V8 is processing a debug callback the thread where V8 is executing is sitting in a tight loop processing debug commands until the continue command has been executed. In some embedding situations it is beneficial to be able to call back into the embedding host from the thread where V8 is sitting. The might have functions which needs to be called to complement the JavaScript debugging.

Using the uint16_t array to pass a void* is a temporary hack.

a09832ab76 Optimize loads from variables that might be shadowed by variables 
introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.

6b4d372696 Added the 'references' command to the debugger protocol to provide access to the mirror features of retreiving all the objects referencing a given object and all objects instantiated by a given function. 
Added commands 'references' and 'instances' to the developer shell for using this new debugger protocol command.

f7f4cb1c33 Fixed the debugger compile events. 
The debugger compile events (BeforeCompile and AfterCompile) have not been used by any V8 debuggers lately and where actually not working any more. Added the correct information to the compile event.

Added a simple 'trace compile' command to the developer shell for testing.

Added a test for compile evnets.
