d46a9900ee Optimizing nested, constant object literals (like JSON objects) by building one large object template for the entire object instead of one for each sub-object.

1418, and 1419 from bleeding_edge until we have a fix
for the crashers we see on the distributed test infra-
structure.

We know that revision 1383 is causing issues, but I 
had to revert some of the other recent RegExp changes
in order to get this part out.

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

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.

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.

20a9e9b013 Change the D8 JavaScript debugger to fully use the JSON protocol. 
The D8 debugger frontend now only processes JSON messages. Before the debugger events was passed as objects.

Changed the debugger events JSON generation to use the same serailizer as the responses to requests. This provides correct serialization of mirror objects in debugger events. Renamed ResponsePacket to ProtocolMessage as it is not only used for responses.

c093e94546 - Pass the knowledge whether the old GC is compacting to the GC prologue and epilogue. This allows us to skip frame cooking and uncooking when doing a mark-sweep GC.
