75bfe56832 Circumvent a bug in older glibc. 
In glibc prior to 2.3.4 the return value from sem_timedwait is not -1
when it fails, but the actual error code.

Turned out that our ARM setup uses glibc 2.3.2.

d7f9992442 Added a wait with timeout to the platform semaphore class. 
The code has been compiled and tested on Windows, Linux and Mac OS.

The FreeBSD version is a copy of the Linux version which should work on FreeBSD as well. According to the FreeBSD documentation clock_gettime is part of the standard C library so the assumption is that no additional link libraries is required for FreeBSD.

37d7dcd20c Add thread information to the debugger. 
Each thread running V8 code is assigned an id in thread local storage the first time V8 code is run in it. The thread information returned to the debugger contains the number of threads, the id of each of these threads and which one is the current thread.

Added a threads command to the developer shell debugger for showing information on threads.

f060eb3293 Changed preemption related stuff in debugger entry. 
Fixed an assertion which did not hold when the debugger was recursively entered.

Removed the clearing of the preemption flag in debugger entry as there was no need for it. The handling of preemption by the stack guard takes care of the in debugger situation anyway.

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.

90093ea868 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.

773843b62e Introduce a BreakTarget subclass of JumpTarget used to represent the 
blocks labeled by "break", "continue", and "return".  BreakTargets are
the only jump targets that appear in the AST, the only ones that can
be uninitialized, and the only ones that can be shadowed.

9d17b0d4c8 Whenever a script object is created it is assigned a unique id. Currently this id is assigned from an 32 bit integer counter. 
Changed the script break points to be able to handle both break points based on script names and script ids. When break points are set through a script id the position is relative to the script itself. This is different from the script break points set through script names where the line/coulmn offset is taken into account.

This has the side effect that function break points are not converted into script break points for named scripts.

Show the script id in the D8 shell debugger when listing all scripts using the 'scripts' command.

Sharing the code to unlink the exception handler for a try/finally
causes us to try to merge virtual frames with different heights (due
to statements that keep state on the stack) at the entry to the unlink

Avoid this by unlinking the handler separately for each exit from the
try block.

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.

dead and should not be emitted.

object. We should start caching scripts but make the
mechanism local to a specific global context inspired
by the way we handle eval-caching.

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.

47b20ddf89 Before emitting code to merge frames, forget the sync flag (telling 
that an element is mirrored in memory) for elements whose target is a
register.  This avoids generating some duplicate merge blocks.
