Change the tests which looks at the number of scripts in the VM after startup to ignore native scripts without name.

Native scripts without name are currently only the script holding the empty script and the script holding the source for the empty function. These two unnamed scripts are created for each context. When running with snapshot an additional context is created during startup adding two more native scripts that in the non-snapshot case.

Mark the empty script object, the script for the empty function and the D8 utility script as native scripts.

This is mainly to avoid these scripts showing up in the debugger when showing normal scripts.

Removed the check for the empty script in the debugger function returning loaded scripts as this check only filtered out the empty script from the debugger context and not empty scripts in all other contexts. Also this filter did not take the script for the empty function into account.

All preemption requests are now ignored while in the debugger. This ensures that no change of V8 thread happenes  while in the debugger. The only thing that happens is that a flag is set to indicate that preemption happened. When the debugger is left preemption is requested if it occourred while in the debugger.

Moved the debugger related global variables from Top to thread local in Debug.

Due to constant folding of loop conditions, it is possible to have a
try/finally with no exits from the try block (eg, an infinite loop in
the try block).  In that case the code to unlink the try handler is
dead and should not be emitted.

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.

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.

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.
